Even if there is life, the likelihood of them evolving at the same rate and in the same form are slim to none. Humans have only been around for about 200,000 years - dinosaurs ruled for millions.
These planets probably have species that look and operate like nothing we've seen before. Or maybe their life forms have already went extinct millions of years ago, or maybe haven't even formed yet.
And in the slim chance that they DID develop into humans, it's funny to think if any of their humans invented the light bulb, or telephone, or any of the advances we made. There's so many ways life can go.
It's fascinating. I love this ****!!!!
