It seems as if you guys are engaging in an endless, round-n-round discussion. A few things here.....(1) Blasphemy, according to the ancient greek text new testament, is when you know the truth(about God) and you deliberately preach the opposite to others below the age of accountability, that's blasphemy.
Now, onto this subject about (2)'is there' or 'is there not' a God.......well, it all depends on your perception. This isn't one of those prove or dis-prove subjects because it's based totally on 'subjective perception'. If I were to say I am God, you couldn't prove it or dis-prove, you'd either believe it or you wouldn't. That is why God the creator has given us free choice. He isn't in it for a popularity contest and he'll never force you to believe......obviously my perception is that there is a God, that's where I stand.
