Does the picture turn when you turn it around?I reject religion because of The Big Picture. The Big Picture, to me, is starting chronologically at the beginning of the Universe and working your way to this point in time, scientifically of course. (If there are any errors in the science please forgive me lol)
Singularity --> Big Bang due to high vaccum pressure --> Stars and Galaxies form over billions of years --> About 9 billion years into the Universe the Sun of our Solar System forms --> Very shortly after, the Earth forms (.05 billion years after) --> the bombardment of earth by asteroids, meteors, etc --> 0.14 to 1.84 billion years into Earth's existence, Abiogenesis brings primitive cells into existence (on its own, no help from God needed) --> For a few billion years these primitive cells become more complex and compete for survival --> transitional forms of cells arise, the transition being single-celled to multi-celled (no help from God needed) --> Multi-celled organisms arise and begin to spread and evolve --> Precambrian --> (okay this is taking a while and I think i'm making my point, i'll skip a bit) --> Homo Sapiens become a distict species in the Homo Genus (we arrived this way on our own, no help from God), also a few subspecies of Homo Sapiens come about but go extinct (they came after us but died out) --> Homo Sapiens spread from Africa to the rest of the world --> We adapt differently to the environments of the world (had our species been isolated we would have branched off from each other, Asians, Caucasians, etc) --> Each culture has its own religious explanation for our origins --> (blah blah the idea is made)
Why, after all of this, does God decide, "hey, those homo sapiens over there are sinful and need to be moral according to my rules"? Why does God put himself in human form in some remote desert part of Earth to die for our sins that weren't committed (Adam and Eve never existed and never 'sinned' against God)? Why after all this time, with all these organisms over billions of years, does God decide that its about time for him to show himself? Why didn't he show himself to the other Highly-Conscious beings that existed in the Homo Genus? What about people that never hear the word of Jesus, are they forgiven for their imaginary sin, you would think that if he was a decent and intelligent God he would show himself to everyone at once to prove his existence? What happens to other organisms in general, when they die do they just cease to exist, saved from hell but exempt from heaven?
Why does God make a heaven and hell for us when the place that we go to is predetermined? God is Omnipotent, All-knowing, and Outside of Time itself, he would already know where we would go to by definition, we have no choice, people like me are doomed to eternal hellfire, do you understand? If we had a choice in what to believe, then the God wouldn't be God, because he wouldn't Know our every thought and what we would decide so that would make him Not All-knowing, A God that doesn't know everything isn't God. If God exists outside of Time, then our existence means nothing to him, the entire history of the Universe could be over in the snap of the finger to God, its like he would have a Tivo remote, he could rewind, pause, fast forward, skip to the end, everything predetermined by the show he was watching that he created, the Universe could exist for .00001 of a second to him, why would he care for a species that arose on earth for a fraction of existence in the history of the Universe. All of that makes no sense though, because the concept of Time is being applied to God! A God outside of Time cannot exist in this way, it is literally un-thinkable, our brains are wired to understand the concept of time, where there is no time it is non-existence to us, our consciousness makes up time, if the atoms in my body were scattered somewhere else in the Universe they would be indifferent to time's existence, they would interact with time but time wouldn't Mean anything to them. If God existed in his own sense of Time outside our Universe (whatever "outside our universe" may mean..) wouldn't he have to be physically comprised of something to exist? If God was Physically comprised of something, in a sense of time, would he be Outside our Universe? Wouldn't those things be applied to Our Universe?
I have yet to have any theist give me a plausible account for the existence of God. I have no reason to believe in God via personal experience. I have no reason to believe in God via the logic that is instilled in my consiousness, if I had a different thought process (different sense of logic) then maybe I would.
Edit: This is pretty much addressing Christianity exclusively.
In your eyes only.
