My belief in a Creator is based on my personal observations of the world I live in. These are the same senses I use to determine for myself (without the need of any "scientists")
Belief in a creator is blind faith. Even though you made a "logical" assumption based on YOUR senses and YOUR observations it's really just one of millions that could be made. Everything in this world is too complex for our tiny minds to comprehend. As comforting/scary as it would be to believe that there is some entity with the knowledge to understand and create all that we know is a silly conclusion to make just like assuming the big bang is fact. You can't possibly know one way or the other. Even your own senses can lie to you. It's nice to BELIEVE we have the answer though.
Not all faith, even faith in God, is necessarily blind faith. One may think that he has powerful reasons to believe in God and, therefore, have strong confidence (faith) in God's existence.
What makes faith blind, meaning dogmatic, is the closing of one's mind to all evidence, logic and reason that may falsify the religion ( A devotion to a principle, philosophy, or any set of beliefs.) in which one has faith. ( Gene's evasiveness is clear evidence that he has no interest in anything that might cause him to examine his faith; hence he's a dogmatist.)
You make it sound as if nothing is really knowable to our "tiny minds" and if by "knowable", you mean beyond dispute by any possible evidence or logic, that would be true, but wouldn't that kind of dogmatic knowing be evidence of a tiny mind at work? Isn't true knowledge that which we have good evidence and reason to believe and even have faith in, with the proviso that it is subject to the expected refinement, modification or outright falsification that will come with further evidence or subtler interpretation?
Before we can have true knowledge or understanding, we must have faith in ourselves as individuals and as humans; in our ability to grow in skills, understanding and wisdom.
I believe that with faith, almost anything, even achievements unimaginable to us today, are possible.
