>>Funny you keep repeating the phrase “you don’t know what a scientific theory is” while not deigning to explain what you think it is—unless you fear disagreement over your definition.<<
OK - a Scientific Theory is a broad general physical explanation of an observed phenomenon — that is off the top of my head and not Googled. We know more about The Theory of Evolution than The Theory of Gravity. We have millions (if not billions) of artifacts that consistently support TToE across multiple disciplines - physics, geology, astronomy (yep), cosmetology — all paint a consistent picture.
>>What is your scientific background, if I may inquire?<<
The thirst for knowledge — and I hang out with some of te smartest people on the planet. I also have a college degree that included both science and theology (graduate level on the latter and my roommate was a theology student).
So, if it is an observed phenomenon, where does that put evolution, which is unobserved?
Gravity at least is observed, has physical laws that describe it and equations that predict what happens when its effect is exerted on a physical body; theoretically, everything that has mass exerts some measure of gravitational pull, with large bodies having sufficient mass to warp time and space around them (the theoretical explanation for orbits).
My college major was chemistry, btw.
