Why speak from knowledge when you can pontificate from ignorance?
I was initially brought to focus on DNA, by my sister. They wanted a male to take the tests. Y-DNA is males only.
So I do tests, and next she too, wants testing.
So fairly recently we both looked at the subject. She tested with Ancestry, and they do "cousin matching."
The matched people were quickly confirmed to be matches. Empirical results confirming the science.
We were brought up with a grandmother who was a biology professor in the 1920s and a mother with a chemistry degree.
BTW the DNA test for Y-DNA confirms exactly the paper version of our family tree for father line. (Haplogroup I1 in central Sweden) Empirical results confirming science.
Finally those females with science training, also taught us that religion and science were NOT mutually exclusive.
