humans didnt appear after the big bang. MILLIONS of years went by. I forgot the analogy but if the earth\'s history was 24 hours, we would only be part of like 2 of those hours.
Your scale is still way off.
One theory holds that the Big Bang occured 13.7 Billion years ago. The Earth formed 4.5 Billion years ago, and our species may be about 5 million years old. Therefore, we only account for about .11% of the history of the Earth. If you thought of that 4.5 Billion years as 24 hours, we would account for about 90 seconds of it.
