In that sense I'm happier in a universe without a higher power, I also get to appreciate all the beauty there is in the universe for a brief period of time and that to me is enough in and off itself.
I think a lot of the reason people believe in religion is fear of nothingingness or an inability to accept that in the grand scheme of things they simply don't matter, basically it's a substitute for having to face death.
The way I look at that is I didn't exist before 1980 and that didn't hurt.. and I fully expect to not exist sometime between now and 2060, the universe was around before me and will be around after me and that's pleasing, given the spectacular chain of events that had to happen in sequence over billions of years for me to have existed at all how could I not.
There is no evidence of God in any of the ways that any of the religious texts describe (and not in any way they don't describe but that's a different subject), that we don't understand the process behind something doesn't mean we just insert "God did it" and stop questioning, your central argument is what is called the "God of the Gaps" argument https://en.wikipedia.org/wiki/God_of_the_gaps and it's notable that over the last millenia those gaps get smaller and more distant in both time and space - we are a long way from angry Gods every time it Thunders and Scarab beetles pushing the Sun across the sky in some ways and apparently no further than we ever where in others, now it's possible there might be things we can never know (there is no reason to presuppose that we can learn everything there is to be learned) but that still doesn't mean we can just insert "Because God" or to put it another way, your claim that God created life has exactly as much merit as my contention that a purple stuffed elephant called Terrence did it since after all it's not on Atheists to prove God doesn't exist, it's on the Religious to prove that he does.
Now this entire debate is pointless since your faith in God requires no evidence (if there was evidence it wouldn't be faith) and my refusal to believe in God (or Gods) is because there is no evidence (or to paraphrase one of my heroes - "That which can be asserted without evidence can be dismissed without evidence") so we reach a natural stopping point in this debate...unless you have empirical proof for the existence of God?.
