However, I think you would admit that having "a lot of evidence" does not necessarily mean having ALL the evidence - the whole story (hence my tagline).
I admit that I muddied the waters of discussion by moving from evolution to origins. However, the point remains.
Certainly we can make extrapolations - even broad assumptions - from the evidence at hand. However, if we accept the idea of a creator, by default then, it behoves us to explore the idea that things may not be as they seem.
In this world, we see a finished product (creation). How we arrived at this product is of course the debate. How would our DNA appear if we were plunked down in the Garden vis-a-vis Eden instead of having been the product of natural selection?
What parameters can we put on the creator? What process does a creator use in the formation of a body, a planet - or the universe. The question really is: what does creation look like?! Must the creator conform to our requirements - or must we discover his?
Last Thursdayism is of no use to science. Sure everything could have been created last Thursday - with false memories and a false history. But such a supposition is of absolutely no use - because going on the assumption that (for example) World War II actually happened - will yield results in terms of knowing and predicting reality.
As to what our DNA looks like - it looks exactly like one would suppose a ‘whatever worked at the time’ collection of some useful and some discarded genetic programs with ‘families’ of similar genes looking exactly like they were duplicates ‘retrofitted’ and adapted to a new use rather than a new ‘perfect’ design de novo.
The Bible says I am created “from dust” and “to dust” I will return. But I was also created via cellular processes involving DNA. That apparently was how God created me “from dust”. Was my creation “from dust” less literal than the creation of Adam from dust?
So, to plant a garden you already need seeds, or maybe cuttings, or could be a nursery somewhere depending on what you are planting.
No doubt God has something like a Tardis (in Dr. Who) which is bigger on the inside than out, with a myriad of rooms with all sorts of things ~ like greenhouses, maybe some studios to cut and paste genomes ~ all that stuff.
