I was born a Catholic but have long renowned such faith. Nearly three centuries ago, the father of American Revolution and the first person to use the words "United States of America," the great Thomas Paine, said the following in one of his books, Age of Reason:
"From the time I was capable of conceiving an idea and acting upon it by reflection, I either doubted the truth of the Christian system or thought it to be a strange affair; I scarcely knew which it was, but I well remember, when about seven or eight years of age, hearing a sermon read by a relation of mine, who was a great devotee of the Church, upon the subject of what is called redemption by the death of the Son of God. After the sermon was ended, I went into the garden, and as I was going down the garden steps (for I perfectly recollect the spot) I revolted at the recollection of what I had heard, and thought to myself that it was making God Almighty act like a passionate man, that killed his son when he could not revenge himself in any other way, and as I was sure a man would be hanged that did such a thing, I could not see for what purpose they preached such sermons. This was not one of that kind of thoughts that had anything in it of childish levity; it was to me a serious reflection, arising from the idea I had that God was too good to do such an action, and also too almighty to be under any necessity of doing it. I believe in the same manner at this moment; and I moreover believe, that any system of religion that has anything in it that shocks the mind of a child, cannot be a true system."
I share this man's sentiment, who was clearly ahead of his time, and go one step further by removing God from the equation as it is not required. You may call me an atheist, but so is the Christian, the Muslim, and the Jew about such gods as Zeus, Apollo, Thor, and Neptune. I just go one god further.
I don't believe in God, let alone any man-made religion, any more than I believe in unicorns and fairies. There is no reason for me to believe. To me, the agnostic position is a weak one because they have not bothered to look at the known and available evidence out there which heavily weighs against the God possibility. It is not a 50/50 scenario. God, like the unicorn, is about 99.9% improbable. I leave a smidgen of a percentage for probability, not for the theistic version of God, but for the God of deism (a creator that does not intervene ever). I don't have to mention the studies conducted on prayer that showed them to be ineffective - one of the first by Darwin's cousin, Francis Galton.
But even deism has its problems. If the universe was created by a creator, this one would have to be created also! So the problem aggravates itself as we are then forced to ask: who created the creator and who created that creator ad infinitum. It's the infinite regress problem. Nobody knows exactly how the universe came about but the afterglow from the Big Bang is still seen in our skies and this colossal explosion was definitely the beginning of at least our universe.
For me, the question is not "who" but "how". The scientific theory that the universe is the result of quantum mechanical fermentation, as it were, is more plausible than a supernatural almighty being conceiving it by magic. If the latter was the case, such creator would have to be extremely lazy (as it took Him billions of years to even concoct the lightest of atoms); unintelligent (one look at our incremental evolution and the defects carried by our gene pool will suffice); capricious or evil/callous (punishment or reward befalls anyone indiscriminately considering wars, extreme weather, wealth etc.)
Anyway, the whole thing is just nonsensical and seems very absurd to me. I've always had a propensity to think for myself (probably my terrible childhood helped with my parents getting divorced and all) and developed an interest in science as I recognised that it was tackling big questions about the alien world around me rather than pretending to know and being intolerant of questioning like religion.
My two cents.
