Mathematically, it's almost a certainty that lifeforms exist elsewhere in the Universe. The pure number of mathematical combination's is so high that somewhere life exists. Is it intelligent as us? Or more so? Who knows.
As for Life after Death? There is no proof of this. There isn't tangible proof of ghosts. Humans have shown the propensity to over complicate or mystify something they don't understand. So what if every religion believes in an after life?
The after-life is the one control mechanism that almost EVERY religion contains. Why would you follow a religion if there was absolutely no tangible benefit to it? You wouldn't. That's why if you don't believe in Jesus then you are told you are destined to go to Hell. That's why if you're a bad person and not Buddhist you will 'reincarnate' as a lower life form. These are all ways to get you to make sure you live a good life according the words in these books. No one wants to go to Hell or Re-incarnate as a Dung Beetle. This is why religion is effective.
This isn't an attack on religion. It's more a line of thought of general logic. How do you keep people to stay faithful and obey a religion? You need control over them in some way. By making them think there is perks to being a part of a certain religion and consequences for not, You effectively have mind control over them.
One thing I know with almost certainty. There are tons of different religions on this planet, Christianity, Islam, Buddhism, Etc. What makes anyone of these specific religions truly believe that they are better or their god is better than the others? If there is a God and we were all created by him, We sure as hell don't know a damn thing about him. And we certainly don't know enough about him so that there is 150 different conflicting stories of him. And lastly, we CERTAINLY don't know specifically that he believed in some derivation of any religion or if he even gave us religion.
