Sorry for your loss, which is this:You are not using the term falsifiable right. The fact that new evidence can disprove evolution is exactly why it IS falsifiable.
If you are going to use a scientific argument, you have to use the terminology the way scientists do. Sorry.
1. it is logically possible that no evidence contradictory to the evolution model exists
2. given #1, it is still possible that the modelled evolution did not occur
3. result: the model of evolution is not falsifiable
These are simple facts.
