Not at all. I do not denegrate faith in God one bit.
You denigrate faith by using it as an insult.
Actually, the ancient age of the universe is the dogma being clutched to.
The age of the universe is a conclusion drawn from evidence, not a dogma. If you want to dispute the age of the universe then please put forth data that contradicts the current calculated age.
There is little differential speed observed in the arms of spiral galaxies, a fact that would be impossible if the universe was 20-30 billions of years old.
Evidence please.
The "answer" is that there must be a "sphere" of matter around the plane of the visible arms to account for the observed rotation. This matter must be "dark matter" to explain why we cannot see it.
Actually, we can see it. We can see it through gravitational lensing as discussed in this article:
SLAC | Bold People. Visionary Science. Real Impact.
Scientists are actively mapping the distribution of dark matter using gravitational lensing.
If you can entertain for one second the possibility of a young universe, then the rotational speed of spiral arms offers no puzzle at all, and is even consistent with the hypothesis.
In a young universe we should not even be able to see these galaxies due to the fact that they are millions of light years away.
