Punkofnice a few years ago I could have written your opening post.
Now I am deeply sceptical about the idea that life is just accidental or that there is no afterlife.
I don't know how but I think there is a direction behind existence. And I doubt we are destined for oblivion, although sometimes that may feel appealing.
One thought I've had for a while is the idea that maybe humans are destined to create ourselves. Since time may not always have existed (a contradictory statement - I don't know how to put it). Or since there may be conditions under which there is no such thing as time. Or time may be a way of looking at things rather than an objective reality.
Anyway since time isn't necessarily the immutable stream we sometimes thought it might be. And since human technology becomes ever more advanced. Might technology and human/artificial intelligence reach a stage where humans can create life, conscious beings, worlds, a universe? If that is possible then maybe we will do so. And if we do so, maybe we have done so, and if we have done so, maybe we are such. Only if time is a linear stream is the idea that we created ourselves necessarily ridiculous. In some ways I think it's the only answer that makes sense. But then again my scepticism kicks in. I'm only suggesting an idea no firm conclusion.
As regards afterlife. If consciousness results purely from the material stuff we are made from, then essentially we consist of information that can be retrieved at some point. If there is an almighty being this should be no trouble for him. If there is no almighty being, but humans become almighty (or some decendent species or conscious being) in the future then he or they would be able to retreive the consciousness and inner life of those who existed. I don't see how this would be a problem. It's a matter of will.
If on the other hand consciousness is more than simply an epiphenomenon of our material bodies then this may suggest that reality consists of more than purely the material. I suspect this may be the case actually. Probably because materialism is such a dominant orthodoxy in the period we live in, makes me suspect all the more that there is something deeply wrong with it. Materialism cannot be proven in philosophical or logical terms, which makes the insistence from certain atheists that we must accept it anyway all the more suspect.
Anyone who thinks materialism is a straighforward, and should be taken for granted way of looking at the world, I would recommend to read Mind and Cosmos by Thomas Nagel. The materialist worldview has a comforting sort of nihilistic certainly about it, which blinds many, who perceive themselves to be warriors fighting irrationality, to its many shortcomings.
