No, you made this statement "So you are saying that you would have preferred to never exist?" I'm saying that we likely exist over and over again, so tossing a deformed body is no biggie, we just move on to the next body.
Why is that likely?
A lot of people have experiences that suggest they have lived a past life. Google it and you'll find plenty.
A lot of people have experiences which suggest they have encountered God, but I'm betting you don't view THOSE as proof of anything.
I'm talking about tangible things, like little kids being able to describe a neighbourhood and everyone in it, when they've never been there. Being able to do math at 2, or play an instrument perfectly at a very young age are tangible things that might be pointing to re-incarnation. What do you have on your god side? Hallucinations? Anything concrete?
No, you're not. You're talking about whatever you think validates your worldview at the moment. IF you think strict materialism will do it, then suddenly nothing exists but the material. Then you decide reincarnation validates you being a self-absorbed waste of oxygen, and you flip on a dime and start rambling about past lives.
The truth of the matter is, whatever comes blibbering out of your cakehole is nothing more or less than "I believe the sun shines out of my asshole, and nothing exists outside of me".
