I'm a little confused by "accepting it as reality", while continuing to look for evidence that it might not be reality.
You're picking at words and don't seem really interested in dialog. Change “reality” to “the best and only explanation to date” if that makes it better.
What are you going to do with the information contained in DNA? Do you have a better explanation for how it got there other than intelligence? Have you seen information arise from any other source than intelligent agents? If so, what is it? If not, what are you going to do with that realization?
Over and out.
