From the Wiki:
"Dogma is a principle or set of principles laid down by an authority as incontrovertibly true.
[1] It serves as part of the primary basis of an
ideology or belief system, and it cannot be changed or discarded without affecting the very system's
paradigm, or the ideology itself."
Even your best "logical and rational" reasoning is little more than subjective personal preference. Those preferences and inclinations are your dogmas. If one or more aspects of your personal preferences change, then your entire life's philosophy goes along with it. does it not?
You believe in God because of "science", as you say, but something as simple as your mindset evolving to see something other than God as the Cause of the Effect of the Universe means that your outlook could be very different in just a few years time.
Your own personal reasonings are yours alone, and only apply to you. As such, they are only logical to you. They are only true to you. You can see God as the Cause of the Universe. You should not confuse that personal preference with science, however.
