Pete- you really have no clue what you yourself are saying

"though of course evolutionism has to keep changing its storyline as more data necessitates it. that's the wonderful thing about it !.
you can change it around to make new data fit."

That is precisely how science works and why YEC is not science

"was,nt it popper who said it cannot be falsified?"

It gets changed around precisely because certain propositions are falsified!

"and is it therefore science ?"

Precisely YES


"is it not rather a religious position ?."

Precisely NO!

With your snarky attempt at derision, you cut yourself off at the knees and prove your utter ignorance of science.
