Honestly guys, you have been coming across as quite rude to the point that I really don't understand what the deal is (not you, Foreigner). There is no reason to be so defensive and judgmental about this, we're in a philosophy and spirituality forum sharing our thoughts. What you've basically communicated, CE, is that someone questioning your idea that consciousness is 100% the result of the brain and that existence might happen outside of your timeframe of physical life, is being an idiot, and that we are certain beyond question that someone believing in continued existence before/after death is either delusional or psychotic. It's really quite an insulting way of communicating about this topic, so you're being called out for that. No one has a problem with you believing that, the problem comes from the lack of respect shown towards another's beliefs. And neither of us is even saying you're wrong, just that we couldn't possibly be certain of anything about this topic. I mean, there are a number of very valid points made against your argument. For example, the lack of the ability to remember something from pre-birth most certainly does not prove there was nothing. There are clear examples of lack of memory where the things that happened are most certainly real.
Science, for some, is a reason to utterly shun the idea that spirituality is a real thing. Yet, many of the most impactful and regarded as the most intelligent scientists over the centuries have been spiritual people. Science and spirituality are not in any way mutually exclusive. Albert Einstein, for example, found the discoveries he made to only increase his feeling of the spirituality inherent in the universe.
Science is a method of thought, a process by which to gain rational understanding of the nature of reality. Science is not ever certain about anything, it is always up for revision. You claim there is zero evidence in science for the reality of the experiences of NDEs, for example, and yet that is demonstrably not true, if you investigate the links above for studies that have been done.
Again, I have no problem with you interpreting the evidence as suggesting that there is nothing after death or before birth, that consciousness is not a property of the universe but a phenomenon totally dependent on the central nervous system. But to claim that we have settled this 100% with science is simply an untrue thing to say, and is a misunderstanding about science and the scientific method itself, and furthermore it is rude and dismissive of the opinions of others when you suggest that those believing otherwise are delusional or psychotic
It's nice to not feel disrespected in discussions, which is all we are asking.
