Noah, I need you to do something for me. I have seen how humanity has been corrupted. You need to build an ark as I will send a massive flood.
God is asking Noah to build an ark as he is sending a massive flood all over the Earth for 40 days and nights. Noah also needs to bring 2 of every animal on the Ark so they can reproduce after the floods finish
The Ark is finished, now, Noah is evacuating the animals and his family onto the ark
The ark lay still in the giant floods. When the rain stopped, the floods started receding. Noah sent a crow to see if there was land. The crow never came back. Noah took this as a sign that there was land to rest.
After sending the crow, Noah sent a Dove to see if there was any sign of land. The Dove came back with a twig which Noah took as a sign that the floods were over.
The floods receded completely and animals exited the ark onto dry land.
After all the animals evacuated the Ark, God promised to never send a flood like that again and made a rainbow to show it.
