Our brain and consciousness is basically just chemical reactions happening between our neurons. The neural network in your brain is what makes you "you"
this is all still speculative though.
Consciousness is one of the biggest mysteries in science. It is not 'basically just' anything as far as we know. Everything is still up in the air when it comes to consciousness. The 'hard problem of consciousness', as david chalmers introduced it, is no nearer to being solved. Maybe it will never be solved. Some very smart people believe it may never be solved (the 'new mysterians', i.e chomsky, pinker, t.nagel, m. gardner, r.penrose).
There are people like r.penrose who believe you have to go down to the quantum and wave functions and microtubles to even begin understanding it, but that is speculative at the moment too, and he still thinks it may never be completely understood. Because it is a bit of a paradoxical task if you think about it, as the only way we can understand consciousness is through the use of consciousness, but doesn't that get you into some kind of Escher-esque geometric conundrum?
There is no grand scheme or meaning to anything
You cannot possibly know this. This is just your subjective opinion.
Everything that occurs and has caused us to be here are mere chemical reactions that has happened over a very long time
This is very probably true, although over-simplified.
But just to add, the materialist hypothesis begs the question as to what 'material' actually means. Because when you get down to the quantum, atoms are made up of mostly empty space (99.99999%), and the subatomic world is weird and counter-intuitive, and seems to consist of information and intangible mathematical entities (Heisenberg said: "Modern physics has definitely decided in favor of Plato. In fact the smallest units of matter are not physical objects in the ordinary sense; they are forms, ideas which can be expressed unambiguously only in mathematical language"). Matter is still a mystery, let alone consciousness.
We have a pretty good idea how life formed on earth, from single RNA molecules to simple organisms, all the way up to complex animals.
But we still have no idea as to how life actually got started from inorganic compounds.
The origin of the line between life and non-life is still a mystery. Some also think that there was far too little time between the formation of the earth and the first prokaryotes for it to have actually originated on earth. But even if life did come to earth on a meteor or something, the question as to how it arose exactly would still remain.
And I don't see where a god fits in here, except maybe making the chemical composition of the universe in the first place. But from that, to there being some omnipotent guy in the clouds being pissed of at homosexuals (or all the other arbitrary things apparently the gods are offensed by), I just don't get it.
I agree with you here
Billions of people has been alive since humankind evolved. I don't like crowds, most people are dicks, I don't wanna be stuck somewhere with all those people for eternity.
lol I get your point.
If God exists, it is a monster.
I like your use of the impersonal pronoun 'it'. I often use it too to refer to 'God' as I find it strange to call it 'he'.
Surely something as unknown and metaphysical and abstract as God should be referred to as 'it'.
Everything we use to understand the universe are just constructs for us to manage reality. Language and concepts don't exist without us, it's how we collectively understand this place.
I certainly understand this way of viewing things.
If a meteor destroyed the earth tomorrow and there were no more humans, the universe would just go on as it is, vast and cold and dark and impersonal, just forces and energy and spacetime warping, for billions of years to come...
