If death (assuming no afterlife) erases your conciousness, it should also erase your memory of ever having been concious. It should be as though you never existed at all, right? Not just future and present gone, but past.
So then how are we here, being concious and remembering stuff? How could that be unless the universe is inherently static, or at least endlessly self-repeating, and us being concious is just a permanent feature of our corner of it?
Has anyone else thought about this or am I just rambling?
Your life and actions exists whether you remember it or not. You will have existed and been conscious whether you remember it or not. This sounds very much in the realm of the abstract and idealism which to me is always a view that focuses too much on our own perception and consciousness and ends up believing that "nothing is real" outside of our perception of it, which I think is a silly if not dangerous view point.
I'm more materialist myself, the material/natural world and what happens in it exists and comes first, our perception of it (and our awareness of our own existence) comes second and is derived from it rather than the other way around in the idealist view.
