I was Bored...

Yeah, so i got bored, so i went on Google Earth and switched it to the sky so i could see all the planets and then i wondered "What if, in other galaxies, there were other planets? And what if there was another earth? A newer earth. Cuz we all know that in like 4.5 billion years, the sun will die during a supernova and its gravitational pull will drag the earth away and basically wipe out our existence. So what if we had the technology to go up into space and go out that far to find a younger earth, so that we could live longer on that earth. What if it was like a copy cat earth? What if we got there and there were like dinosaurs and cavemen? Sounds cool right? Hm. If only.
