What if you were dropped into every era of Earth? You stand on one rock while 4.5 billion years pass: lava, lightning and falling meteorites, a green sea, ice to the horizon, a golden swamp of giant horsetails and crawling giants, and dinosaurs at a river. Then a meteor comes. For about 47% of Earth's history there was no free oxygen in the air. In the first three eras you would last well under a minute. #whatif #pov #simulation #science #3danimation #earthhistory #dinosaurs #prehistoric #fyp
