No, the Earth was uninhabitable for millions of years.
Life did not start after the dinosaurs were wiped out. Life on Earth started billions of years before that. The asteroid wiped out a large portion of life on earth, but not all of it. Some things survived.
He said let there be life and there was, it was in Genesis.
When life on earth started.
3.5 billion years ago that's when the earth was cooled down
life first started from bacteria that is in a human body and it starded life on the earth and it is true.
All life on earth uses water from the moment it begins.
I believe life will begin on mars. And earth will turn into a planet like mars. as earth is moving closer to the sun. No, read a bible dude!
The first sickness was probably due to a bacteria, since they were the start of life on earth.
If you mean how did life start then no one can answer this because no one really knows there are a few possiblities like germs evolved or maybe a metorite crashed into earth which contained life forms but maybe we will find out some time in the future .
There will always be a start and an end to something. Eventually, the Earth, our Sun, our universe must end. Maybe to start a new universe and new life somewhere else. Thankfully, as it is many billion of centuries in the future (fingers crossed) I won't be alive to see it happen.
No one really knows when people started showing up on earth, but there has been people on earth for at least 100 million years!
Life is on earth of course
