If you have a BS in biology you understand the level of modification done here.
It's only a matter of time until a fully artificial form of life is created, or do you think only god can do that?
It's cool. I go off on people sometimes too.
There is no God, and you're right, it's only a matter of time. Let's not jump the gun though. It just makes scientists and atheists seem like we don't know what we're talking about.
So now we have artificial chromosomes that are almost as sophisticated as viruses. I say almost because they need to be manually placed inside the bacterium.
We know how phospholipid bilayers come into being spontaneously. We know that the polymerization of nucleic acid is spontaneous given enough NTP concentration. We know how the phospholipid bilayer (aka cell membrane) selectively absorbs small molecules while holding on to the big ones. This is the predecessor to "eating" or "absorbing through the roots" I imagine. We know how either nucleic acids or proteins can act as enzymes, and protein polymerization is spontaneous just like nucleic acid polymerization.
Miller-Urey and the like showed how one gets the NTPs and other small molecules needed for all this from what we believe to be the early Earth atmosphere or one like it.
We know a lot of bits and pieces, but we're not quite there yet.
I won't be satisfied until I see a recipe for making self replicating cells starting with a Miller-Urey type synthesis of the small molecules from "water (H2O), methane (CH4), ammonia (NH3) and hydrogen (H2)." (or something similar).
