Thanks for the background posts; interesting stuff.
Also, I see and understand your point re "beautiful planet created for us". We are intrinsically tied to our enviroment and arose from it, thus everything in it has a natural order and beauty to it, not necessarily because it was created but because we arose from it and this is how natural selection and processes work with us being a part. If we had evolved on Venus, we would see sulfuric acid rain, 400 deg temps and intense pressure as being the norm and would've evolved accordingly.
As for the beginning of the universe, the idea of the Big Bang is largely due to taking observations about the current state of movement and expansion of the universe and working the math (and time) backward to a point, in a sense. This idea is not subjective speculation (as is god and creation) but a reasonable calculation based on known physics observed. As in black holes, these laws of physics break down at the point of t=0 and do not adequately describe how it worked before then, only that these laws exist now and have an immutable effect on the reality of our universe. Our known laws do not explain what or how things existed/didn't exist before or at t=0. Quantum and super string theory has made strides into possible explanations for this but is as yet unproven.
From what I know, it's still a toss up as to the fate of the universe; whether it will stop expanding and reverse motion into a "Big Crunch" or hit breakaway velocity and blow itself apart, a "Big Chill". Apparently it depends on the ratio of dark matter to dark energy, both of which are needed to make the math fit the observations made but the nature of which is still in question and in the process of discovery.
Interesting times in the history of man to be sure.
As for the concept of time and dimensions, wrap your head around this
