There are two things going on here:
1) Your explanation is not incompatible with theism. A theist could easily say there is a biochemical and theistic foundation for spiritual experience. They are not mutually exclusive.
No one said they were. We
have stated, however, that theism posits the existence of an entity for which there is neither need nor evidence.
Theists will tell you that god is easily detectable, when they pray and whenever they experience god's presence.
And yet they have no evidence that they are actually experiencing God's presence rather than simply believing that they do.
You're already assuming such experiences are not evidence because you've adopted the scientific atheistic viewpoint
No. We're assuming that they aren't evidence
because they aren't evidence.
A man on an acid trip claims to have spoken with John Lennon. Without further evidence, the only rational conclusion is that he did
not speak with John Lennon. He simply hallucinated doing so.
Is it technically
possible that Lennon talks to people while they're tripping? Yes. Is it supported by the evidence? No. It's the same thing for your argument about personal experiences.
but that's the very thing you're trying to show is "more likely".
We've been over this. More rational.
3) You're claiming there is no evidence for god. Again, this reveals an assumption on your part: that reality is materialistic. If reality is a projection of God's mind (Berkeley's idealism), then there is copius amounts of evidence for god.
No. Do you know what "evidence" means?
Even if reality
is a "projection of God's mind" (whatever that gibberish means), the existence of reality would not be evidence for God. You would still need some way to show that the idea is true. The mere existence of a universe does not support that idea.
And so on and so on. The rest of your posts thus far have largely been a repeat of the above points.
