It sounds to me like you are describing a process whereby 'God' has been created in man's image...
Good point, I understand what you mean. And this impression can also be said if someone was describing a statue of you. The description of you and one statue of you could be hard to differentiate.
And by the way...belief in such a god as you describe requires 'faith', not rationality.
To believe universe itself can be understood with human reason requires faith too.
And that's what we do.
There's no warranty or proof of ANY kind I will be alive tomorrow but my plans and my thoughts are made upon faith that I'll be alive in next years.
Faith itself it's not a bad thing, but I agree with you that faith in some premises can be harmful.
The premise of faith is that our rational minds can't be traceable to any animal and our minds can bear the concept of infinity. It's logical to conclude our rational minds came from something higher.
