Nothing After Death
If we're disregarding religions, and looking at death from a scientific angle, then there supposedly is an answer; that being that there's a whole lot of nothing after death. The way I came to this conclusion is how everything is made of atoms, including your brain, and matter cannot be created or destroyed. This means that atoms make up your consciousness, and is just recycled, rearranged atoms from before you were born. This would mean that after those atoms forming your consciousness disband, they just get recycled again. Your consciousness would literally be broken apart and those atoms form other things later on after your body decomposes. This would mean that death is only the space within atoms, which if you aren't there to witness it, would allude to the point that there's not anything after death: just the space of where atoms form. A void if you will. Though, this is just a thought, and we don't quite know where the root of consciousness is yet (or at least I don't think so, lol). My brain also kinda shut down the philosophy mode halfway through so I couldn't truly say what I was previously thinking, only what I remember thinking.
