First things first, it wasn’t a UNIVERSAL FLOOD, it was described as a world-wide flood. You have take the biblical hyperbole to a whole new level.
Second,
Think your recent flood theory through and follow its consequences.
I’ll keep variables very simple.
Theory
1. Recent flood ... say less than 10k years ago.
2. Limited gene pool of animal life (only those on the ark).
Current environment
1. A wide genetic diversity
2. Multiplicity of animal types
Conclusion:
It’s true, current evolutionary theory can not explain the diversity of animal life if there was a young earth and a recent world-wide flood.
SO....Creation science doesn’t mean “NO EVOLUTION”, it requires a quantum-force evolution in order to explain the current environment.
