By space ship we were dropped off about 16,000 years ago.<br />
About 150,000 and then 80,000 years ago drops were made and all died out.<br />
But only after two other tests that failed as the atmosphere was still developing.<br />
The third test was just a short time ago and we had a super atmosphere the planet heated up and created a tropical environment.
God dropped a duce, we're the critters devouring it
scientists,we are still onto it.wait for the answer next year
Byrdistheword sums the universal & planetary origins up pretty well. In a sort of nutshell. Then after that we get 3,000 million years of evolution of life to bring us down to where we are today.
after the big bang all the dust started clinging together to make rocks, rocks made boulder, boulders made mountains, and mountains made planets. Luckily earth was given all the different materials needed to make life like water and other stuff. I don't know how life started, i heard lighting hit the ocean once and started the first micro-organisms but there are probably lots of opinions. Idk
The ultra-mega-unicorn laid an egg that hatched the universe, which the Earth, and us are part of. Everyone knows that.
