You clearly have no understanding of science or how it works, this unfortunatly makes your points on science invalid.
Educate yourself about the scientific community and method before you make comments about how it works. You are simply uneducated on the subject and are making incorrect statements.
I seriously suggest you watch this video to educate yourself about the basics:

As for how science explains NDEs read the later work of Susan Blackmore for a very interesting take on the subject. She was a trained scientist who had an NDE, so dedicated 20 years of her life to "prove other small minded scientists wrong"... in the end, she had to conclude that there was no evidence to support it. Research her.
Science never EVER finds something that "pisses it off" - that is absurd. Educate yourself before you criticise the very way of thinking that has allowed you to post on this forum, watch TV, call your friends, get medical help, sent men to the moon etc. etc. etc.
You can't pick and choose the science that suits you. If you disagree with science go live in a cave and let your "spirituality" sustain you. You wont need a mobile phone because you'll just be able to astrally contact your other spiritual friends.
No? oh why not? BECAUSE ITS NONSENSE.
Live in a delusion if you like. But don't get defensive when you share your delusional views with the rest of the world and they start pulling it apart with facts and evidence to the contrary.
Of course you'll have to accept science to be able to reply to me, which must really piss you off.
Or was the internet born from a spiritual revelation?
