God isn’t mentioned as creating many things specifically- just everythign in general, and some htings specifically.
Seeds can survive soakings, even sprout on sludge rafts later to take root dry land. pollen also survives. Acorns can survvive, some trees can survive being submerged for weeks- on and on it goes- many can.
A very few can, most can’t.
Mosses, ferns, liverworts, fresh water algae, most angiosperms can be downright persnickety.
Fungal spores last, but they have to wait for their hosts to grow.
Maybe they’ve all evolved persnickety-iness since the flood.
Funny how God is only mentioned as creating things folks were already familiar with. No mosses, no ferns, no algae, no fungi, no slime molds. Just “animals” creatures of the sea, and seed bearing plants.
