We used to get blitzed and joke like 60s liberals about ‘Infinity....like wow man” when I was a young lad. But when you seriously ponder the number of stars, much less planets...Ouch. Serious brain hurt.
There have to be MANY earths out there. VERY many.
An infinite number of universes?
An infinite number of identicalineveryway universes?
Now I am really angry!
I read many sci-fi novels in my youth, many about this concept. The ones I remember most are of aliens traveling to Earth-like planets and only finding long-gone and dead civilizations. So many billions of years have gone by, and perhaps many civilizations have come and gone but none "nearby" while both are in existence. And "nearby" could mean millions of light-years distance. Maybe God wants it that way.
