I can vouch that a humble cell is the best proof of the existence of a Creator.
Based on what?
You need to do a serious study of the cell. Just to give you an example, I spent several class periods explaining to my students the importance of accurate replication of DNA, and we looked at all the mechanisms by which the cell double proofs newly synthesized DNA to make sure it is a perfect copy of the parent DNA. But then we looked at RNA, how far less importants the effects of a “mistake” would be, and how much more relaxed RNA synthesis is. We even discussed how many “mistakes” in RNA synthesis either don’t make any difference, due to wobbling of the 3rd base in a codon, or the difference is minimal (change an aminoacid for another one that most likely will have similar properties). At the end, it took me close to an hour to compare both processes, and I challenged the class to think if “it just happened so”. That’s just one little example, you may want to sign up for my intro biology course, provided there are openings, it has turned out to be quite popular. How frequently do you get to see a professor raise her hands and proclaim “my Lord, how great Thou art” in class?
