Fun to think about another Earth. I hope it's like this
Even if it was void of life, but able to be inhabited would be incredible. Then to think if it did have life on it. They look like us, or different alien like? If they were more advanced and we could learn from them, or more primative? Or if they looked just like us, but were instead very different personalities like extremly rude or short tempered, even violent.
Or maybe everything is normal, but they do something we deem, strange, like masterbating in crowded public places. Or giving eachother golden showers every day at 5:00 pm no matter where they are? Would give a whole new meaning to "It's 5 o'clock somewhere".
I like to think it is a parallel world of our own lives where we can meet our doppledonger and each see how our life could have been had we taken a different turn, or some things been different. lol
