We've had over 4,000 religions on this planet alone.
There are at least 100 billion galaxies in the universe, and likely MANY more than that. Even if there are just a few planets in each galaxy supporting intelligent life, that would likely mean that there are trillions of religions. And there are probably more than a few in each galaxy, so the # may as well be infinite.
And some religions here that are only a few thousand years old think that their faith is the only one that matters, or that grants passage into the afterlife?
It's insanely illogical. Organized religion is a pretty primitive thing. We should grow out of it.
