Why are Christians scared to die?

On the conscious surface, no. I believe you are a genuine person.

He's talking more about what is really going on in the replitialian part of our brain.
We have no control over this. 100% instinct. It bypasses any/all indoctrination.

Don't believe me, intentionally walk towards a wall at a constant speed with your arms at your side until you hit it.
The lizard brain will keep you safe and alive.
The lizard brain knows that this is the only life you have.
4 billion years of evolution programmed in your DNA days so.

How can you claim that deep down in my subconscience I "know my beliefs are all BS?" 

Having a natural fear of the unknown and a will to survive doesn't conflict with religious beliefs at all.

You don't know your beliefs are bs. Indoctrination teaches you to ignore the lizard to an extent.
If you did know, you'd be atheist.

We tend to follow our instincts. If it smells like bs, etc
