If a single celled virus mutated into something more deadly and resiliant than a strain of it's predecessor, then it would have to reproduce through splitting from the newly designed cell.
If it reproduced.
This would create a new "creature."
Would produce death or weakness to the cell. Cells are powerful, but powerful in attempting to regain the perfection that they had. That's the reason life keeps on going. It is attempting to get back to the perfection that it once was. Will never make it. Death will keep on happening.
Is that proof that some god somewhere has made that happen? Of course not. It simply means that the cell naturally needed to evolve and adapt to it's envoronment and did so.
Having a "need" is more like "being designed to have the need."
Thats just a microcosm of what happens with multi-celled organisms over time.
As I said above, in this post.
Humans still have appendixes which perform no real function for us today, but they were useful for something at one point in our evolution.
Actually, the Chinese found out ages ago that the appendix produces a slime that covers the stool so that the stool doesn't harm the colon wall as it passes.
Some harmonic studies that compare plants with animals suggest that the vibratory rates of the appendix match those of plants that propagate through "appendages," like strawberries and some vines. Perhaps before the fall into sin, people would have propagated like this.
Some god isn't just twitching is nose and making things happen. Things happen for scientific reasons.
This is absolutely correct. God is way more scientific - from the currently evolved common meaning of "science," not the dictionary definition - than man is. Yet, from man's "dictionary science" meaning, God has made the soul of man so strong that He does examine the heart to see exactly what kind of faith exists there, person to person.
