At the start of making this topic, I specifically said:
“I really need to know from expert scientists whether this experiment could potentially test for a Universal common designer existing in biology.”
At some point, I added the introduction to help reviewers adequately critique my case.
This means that I never pretended to be an expert this field nor do I have a desire to be one. You either did not care to read this or did not fully absorb it into your brain. For this reason, I don’t care whether I make mistakes or not but I care about getting the mistakes right. So I’ll admit I was attacking a strawman argument in regards to their article because I was ultimately focused on trying to make a larger point, as a NON-expert, to get expert advice. However, unlike other users on here, almost all your objections and sources (except for one maybe) have NOT addressed the topic at hand. Therefore, I am only going to address the things you said that are relevant to the topic from here on out.
Yes, I agreed but what was the point of your objection in regards to the topic. Do you agree that my proposal can be tested in a way that verifies or at least potentially falsifies the hypothesis that a Universal common designer exists in biochemistry? If you do, then I encourage you to move on from this and politely ask you to start critiquing the next topic I made:
