Religion as a choice

I am totally sick and tired of people who, use every opportunity when God is mentioned in any way, to preach their own personal beliefs as if they were an unquestionable fact.
Recently, a family member, who apparently is a believer, announced to the Face book world that she had gotten rid of a bad relationship and was starting anew. She had mentioned how she believed God had helped her to this decision. Fair enough you might say, and I would agree. If she believes this to be the case, its her prerogative and she has every right to voice this any way she desires.
I added a word of encouragement to her, stating that if their is indeed a God, he would undoubtedly be happy that she was making the right decisions to be happy in her life, and would be smiling on her.
This comment was met with indignation from more than one, in my opinion idiots, who took this opportunity to spout a barrage of scriptural quotations and apparent outrage that I would dare to assume that God may not exist..
It is my humble opinion, that we are all born with free will. This has to include the right to choose to either believe in a God or not. Or indeed as some of us do, choose to sit on the fence as we do not to pretend to have the answer. The official title that society label us with is I believe Agnostic.
I would never be pretentious enough, as a mere human being, to assume that I could ever know for a fact that a creator does or doesn't exist. I have, as I am sure many of you have, often stared at the splendour of a night sky in all its glory and wondered how far the universe went, how many suns, planets, Galaxies and perhaps other universes, actually do exist.
The scientists tell us that even with the super telescopes that we have created today, we cannot see even a small fraction of what is out there. The human mind, in not capable of understanding the vastness of space or our minute part in it. So, how can anyone say for absolute certain, as an indisputable fact, that God exists and created it all?
We are all entitled to believe whatever we want, and man has attempted, since we were able to walk and talk, to explain it all.
Many writings on the subject, the Bible, the Koran, the Buddhists writings, Hinduism, Muslim, and on and on, all have theorised on mans creation and the creation of all things.
None of these agree in total and none have given a Universally accepted theory of the "facts" because we simply do not know. We probably never will, unless the day comes that we are all actually called to a judgement, and have that "oh shit" moment. Or perhaps the Roswell aliens will come back and land on the Capitol lawn to explain it all to us, who knows?
In the meantime, please spare me you pious ramblings about the "fact" in your minds, that God is real.
You, my religious fanatic friend, know no more than I do, and your conjecture and judgement of others will always be met by a healthy dose of questioning and some pity towards your narrow minded approach from this blogger.
Until my next ramblings,
Farewell.
