You don't what what I am saying.
We can't have science if we don't know how to use it.
If religion is the only way give us the morale and ethics necessary to use well Science, then, so be it...
I don't think it is, though.
I mean, do you imagine what would be of us without moral, and having weapons of mass destruction?
BOOOM, Hiroshima. Yep, already happened.
Religion isn't that useless. It's stupid, but not completly useless. At least for dumb people, that believe it to be true...
As Karl Marx, or Lenine, can't say for sure, said, The religion is the ophium of the people.
