And I'd respond by saying the fact that all of this is way beyond our little minds' ability to comprehend. And given that so much about the infinity of time and space coming together in this moment of life is beyond our comprehension, you look rather silly when you claim to know, by your observations with your five senses, that you have it figured out, and have concluded without a doubt that time and randomness explain all. Agnosticism is a respectable position. Atheism, especially the brand that likes to use mocking phrases like "magical being in the sky" is is the embodiment of human arrogance and folly.
No one claims to have known it all, other than people who put blind faith in the ramblings of other people thousands of years ago, and then derive an explanation for everything, purely out of those.
That would be arrogance, and not the intent of trying to explain the things around us using evidence available to us.
Agnosticism / Atheism are the same, more or less. My position is only absolute based on how much I know, right now. If a god appeared this instant and showed me something that I couldn’t explain, my views would change in an instant.
