I suspect there are vast planes of existence/dimensions that are out there, and we are only beginning to even formulate the ideas - let alone know what they are. Consciousness could very well be connected to these other planes/levels. This is not magic. It's possible undiscovered science. I love the notion that 500 years ago no one had any fucking clue about radio waves. Even if you'd tried to explain it to the smartest people on the planet, they would have been like WTF? 1000 years ago people couldn't even IMAGINE undiscovered science. The current generation always thinks they've got it all fucking figured out. Without exception. Foolishness.
In 500 years, we're going to have discovered the most amazing and fantastical shit that...right now...seems utterly preposterous. Existence of God? Gods? Super Higher Power(s)? Consciousness that continues? We say pfft now, but....
I'm just going to leave these there before I go: Clarke's Three Laws:
1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
3. Any sufficiently advanced technology is indistinguishable from magic.
saving the planet from being taken over by robots, of course!
