Facts
1. Jesus was a real person.
2. His teachings didn't include killing in the name of God.
3. He had 12 disciples.
4. These men dedicated their lived to the beliefs of Christianity. To the point they gave up their normal lives completely to follow Jesus.
5. Lying was something they were very much against.
6. Several of these disciples documented in writing that Jesus was the son of God. That they witnessed him perform miracles.
You call BS when people say Christ performed miracles. But his disciples are the ones that documented them. Men who, by telling a lie, would go against the very thing they devoted their lives to.
Facts.
Fact, accounts shows Jesus only lived 6 months after his revelation in baptism, and looked arabic, someone you would assume to be muslim and be afraid if you heard him say something that sounded a little like 'bomb' in an airport.
Fact, there is no evidence that Jesus arose from the dead, some of his disciples became convinced they had seen his spirit after he died and it went to heaven. Christians have since interpreted this as being 'resurrected from the dead' yet we believe that all souls rise from our bodies when we die and go to heaven or hell, not just Jesus.
How do you know it NEVER can?
That's a questionable claim.
Because it simply can't, by the same principle that you can never prove that God does not exist.
I'm talking about questions such as what is the meaning of life? Why are we here, etc? For those of us who don't feel "because a bunch of atoms exploded and somehnow we ended up here and its totally meaningless and I might as well kill myself right now because it really makes no difference" is a good answer.
Questions about right and wrong, questions about how we should behave and act as humans, etc...there is nothing scientific about killing that makes it wrong, nor stealing, nor assaulting, nor any of the other things we consider 'civilized'. There is no science behind it, it is purely based on opinion, or belief, aka religion. Religion is not just specific 'religions', it is religious thought. It is pretty much anything that is not scientific or artistic, with some overlap.
