How many years did it take Noah to build the ark?

It took seven days. The following is taken from "Noah's Ark" in Genesis. God ordered Noah to build an ark. God saw that man was guilty on the earth, and all he thought all day was evil. God regretted making man on the earth and was sad. God said, "I will destroy man and beast, insects and birds in the air from the earth, because I regret making them." Only Noah was favored by God. God looked at the world and saw that it was corrupt; All human beings have fallen on the earth. God said to Noah, "the end of all flesh has come to me, because the earth is full of their violence, and I will destroy them with the earth." Make an ark of gopher wood and divide it into rooms, and coat it with rosin inside and outside. This is how the ark was made: 300 cubits long, 50 cubits wide and 30 cubits high. Above the ark, let there be light, one cubit high. The cupboard door next to it should be open. The ark should be divided into three layers: upper, middle and lower. Behold, I will drown the earth and destroy the whole world. All living things on the earth that have the breath of flesh will die. " But I want to make an agreement with you. You, your wife, your son and your wife will all enter the ark. All living creatures, male and female, are to be brought into the ark, so that they can save their lives with you. All kinds of birds, all kinds of livestock, and all kinds of insects on the ground, two of each kind, so that they can save people when they enter you. Bring all kinds of food and store it for you and them. "Noah just do it. He did everything God told him. When Noah entered the ark, the LORD said to Noah, "You and all your family shall enter the ark, and you will be regarded as a righteous man before me in this generation. All clean livestock, you should take seven males and seven females; For unclean animals, you should take a male and a female; Birds in the air should also bring seven males and seven females, so that they can keep their seeds and live on the whole earth. For in seven days, I will rain on the earth for forty days and forty nights, and I will destroy all the living things I have created from the earth. "Noah did as the Lord commanded him. Noah was six hundred years old when the flood flooded the earth. So Noah, his wife, son and wife entered the ark to escape from the flood. Clean animals and unclean animals, birds and all the insects on the ground came to Noah in pairs, male and female, just as God had commanded Noah. After those seven days, the flood flooded the ground. When Noah was 600 years old, on February 17, all the fountains in Tianyuan cracked and the windows in the sky were opened. It rained on the ground for forty days and nights. On that very day, Noah, his three sons Shem, Ham and Japheth, Noah's wife and three daughters-in-law entered the ark. They and all animals, according to their species; All livestock, according to their species; Insects crawl on the ground, according to their types; All the birds, according to their species, entered the ark. Every living thing that breathed came to Noah in pairs and entered the ark. All flesh and blood entered Fontaine. They were all men and women, just as God had commanded Noah. So the Lord shut him in the ark. The flood flooded for forty days, and the flood flooded the earth for forty days. The water grew up and floated the ark from the earth. The water is vast and long on the ground, and the ark floats on the water. The water potential is so vast on the ground that all the mountains in the world are submerged. The water is fifteen cubits higher than the mountain, and the mountain is submerged. All flesh and blood on the earth, birds, livestock, wild animals, insects and all people died; All the breathing creatures on the dry land died; All living things on the earth, including people, livestock, insects and birds in the air, were wiped out from the earth, leaving only Noah and those who begged him in the ark. The water is vast, and there are 150 days on the ground. When the flood receded, God remembered Noah and all the animals in Noah's ark. God told the wind to blow the earth and the water gradually fell. Yuanyuan and the windows in the sky are blocked and the rain in the sky has stopped. The water gradually receded from the ground. After 150 days, the water gradually disappeared. On July 17, the ark stopped at Mount Ararat. The water gradually disappeared again. On the first day of October, the top of the mountain appeared. Forty days after Noah released the crow and pigeon from the ark, Noah opened the window of the ark and released a crow. Crows flew around until the water on the ground dried up. He released another pigeon to see if the water had receded from the ground. But there was water everywhere, and the pigeons couldn't find a place to stay, so they went back to Noah's ark, and Noah reached out and took the pigeons into the ark. He waited another seven days before releasing the dove from the ark. In the evening, the dove came back to him with a freshly twisted olive leaf in her mouth. Noah knew that the water on the ground had receded. He waited for another seven days and let the pigeons go. They never came back. By the time Noah was six hundred and one years old, on the first day of the first month, all the water on the earth had dried up. Noah uncovered the cover of the ark and looked, and the ground was dry. By February 27th, the land had dried up. Noah and his family walked out of the ark. God said to Noah, "You, your wife, your son and your wife can all go out of the ark. Everything that has life among you, birds, livestock and all the insects that crawl on the ground, should be brought out, so that they can breed on the ground and flourish every day. So Noah came out with his wife, his son and his wife. All the animals, insects, birds and all the animals on the ground, according to their kinds, also went out of the ark. Noah built an altar to the Lord and offered burnt offerings on it, as well as all kinds of clean livestock and birds. When the Lord smelled the sweet smell, he said in his heart, "I will no longer curse the land because of people (who have evil thoughts since childhood), nor will I destroy all kinds of living things as before." When the land still exists, crops, cold and heat, winter and summer, day and night, never stop. "God bless Liu Ya. God blessed Noah and his sons and said to them, "Be fruitful and multiply, and fill the earth. All the animals of the earth and the birds of the air will be terrified and frightened because of you. Even all the insects on the ground and all the fish in the sea beg for your hand. All living animals can be your food, and I gave it all to you, just like vegetables. But the flesh with blood is its life, and you shall not eat it. I will punish those who shed your blood and killed your lives, whether they are animals or people, or even their brothers. Whoever sheds blood, his blood will also be shed by man, for God made man in his own image. Be fruitful and multiply, and prosper in the earth. God said to Noah and his sons, I will make a covenant with you and your descendants, and all the living creatures here, including birds, livestock and wild animals, and all the living creatures that come out of the ark. I make a covenant with you, that all flesh will no longer be destroyed by floods, nor will there be any more floods to destroy this land. In memory of God, Li Hong said, "My everlasting covenant with you and all living things here is marked. I put the rainbow in the clouds as a sign of my Covenant with the earth. When I cover the earth with clouds, a rainbow will appear in the clouds, so I will remember my agreement with you and all living things, and the water will no longer overflow and destroy all living things. The rainbow will appear in the clouds, and as soon as I see it, I will remember my eternal Covenant with all kinds of creatures on the earth. God said to Noah, "This is a sign of my Covenant with all flesh and blood on the earth." There are many evils in the world, so God decided to make a "purification". Because Noah did the least bad things, he ordered him to build a huge ship and take all the animals with him. Soon the flood purified everything. Only Noah's ship escaped, and the animals on board returned to land to start a new life.
