Do you know what astrophysics is?
Yes I was making an analogy to the argument that "beliving in creationism does not make one less capable at genetics" which is also true.
I'm not sure if I see which side of the creationist arguemetn you are on, but I will say that creationism and genetics do not mix. Genetics is supported by evolution and is used to establish ancestral relationships. If you believe in creationism, then you cannot, in good faith, understand genetics.
If you believe in a geocentric universe you will not succeed at astrophysics.
And in the same fashion if you deny that life forms do not adapt to their environment or that genes can mutate, you will not succeed at genetics.
OTOH, the belief that a designer better explains the universe and the diversity of life than solely natural, observable forces is no inhibition to any study of science.
