You cannot replace something with nothing. Scientific explanations are useful and predictive. Creationism is useless for explaining or predicting the natural world - it is a mindset that leads nowhere and to nothing rather than prompting further innovation and discovery.
How did the marsupials all end up in Australia? How did all modern species descend from those few that could fit on a boat of known dimensions without extremely rapid and powerful evolution and common descent of species (within a “kind” that they cannot ever seem to define).
Add to that the mystery of Antarctica and plate tectonics.
It must be nice to have adherents that demand an ever higher and higher burden of evidence from the other side, but are content to never ask or answer the hard questions on their own side.
