"I have made several valid scientific arguments supporting the hypothesis"
They're only valid because you say they're valid, but they all boil down to things you can't explain, so you insert God (you don't mention God, but the implication is as clear as can be).
For example, when you say that many has always worshipped something, you assume that must mean there "is" something, and fail to consider other possible reasons for man's history of spiritual belief (fear, explaining the unknown, the need to bring order to what is an incomprehensible universe, etc.)
No, actually I use the tested theories of one, Charles Darwin, who states in his
Theory of Natural Selection, a species evolves by retaining fundamentally desirable attributes, while discarding undesirable attributes, as they relate to the survival of the species. Indeed, man does operate on logic, and does need an explanation for how such a diverse and complex universe came to be, and this indisputable fact is the basis for considering the possibility it was created by intelligence.
There is no valid logical reason for man's retaining spiritual belief, unless it is fundamental to human survival, and every indication is, it has been. In fact, a noted psychologist once said, mankind is so connected to spirituality, if there were no such thing as God, we would have to invent him. Man could simply not exist in a Godless world.
NOTE: When I use the term "God" here, I do not mean or intend any particular perception of this entity, rather the concept in general, of something greater than self, or a supreme power.
Biological and Psychological evidence is Science. As much as you wish to deny it, or claim it hasn't been presented, or try to spin it into something other than science, it is still valid and legitimate scientific evidence to support the argument I have made. It all boils down to what you personally have faith in. Myself, I try not to make scientific
assumptions and conclusions on personal faith, I think it is detrimental to knowledge and science. I tend to leave the possibilities open, and continue to explore them all. Including the reasons for the very real and profound connection man has, to this idea we were
'created' by something much greater. It's just a possibility I can't refute or conclude is not there, and it has very valid and legitimate support.
In order to see this from my perspective, you must remove the roadblocks you've established in your mind. You simply can't conclude man is connected to spirituality to 'explain the unexplained' and not continue to ask, why is this so? We can observe that no other species of life does this, it is a unique quality of mankind. Why do we have this fundamental "need" to explain the unexplained? Where did this attribute evolve from? Dogs, Horses, Monkeys, Fish... don't have any "need" to explain the unexplained, especially not to the point of creating some 'mythical figurehead' to worship, in order to do it.
You see, you have stopped asking questions because you have drawn a conclusion, largely based on your own personal faith. This is not how mankind has ever achieved anything in Science, to my knowledge. You must always continue to ask, why? Why does mankind have to create Gods to explain the unexplained, what difference does it make, particularly if there is nothing to it? Why don't other primates have to explain the unexplained by developing worship and spirituality? Can you explain this? I can't, because there is no explanation. Theoretically, according to Darwin, we should see some indication of this trait, in lower 'ancestors' of our 'family tree' and we don't.
Why?
