These arguments beg the question and are ad hoc attempts to explain the evidence.
False. You just want to declare any other belief than your own ad hoc!
There is no evidence for a world-wide flood;
Plenty. The worldwide legends and accounts of one. God's word about what happened, confirmed by Jesus. The fact that there is no evidence against it. Possibly the KT layer iridium which science says is sourced from the same places floodwaters came from-space and deep under the earth Etc.
the Genesis flood was probably a local flood (one of many in recorded history) in the valleys of the Tigris and Euphrates).
No. It clearly killed all animals and men on earth.
If you think that 'man and MOST animals on earth, and most plants also, ... could not leave ... fossil remains', you should present some evidence.
If you claim they could you need to prove nature was the same then! Otherwise, we all just believe wat we like.
The story of the 'confusion of tongues' at the time of the Tower of Babel is pseudo-history;
It is stamped with the approval of God. It fits the evidence such as where cultures religions and customs and languages came from.
there were separate languages long before the foundation of Babylon,
Prove it. Your dates will crumble like soda crackers.
and the idea that the Earth's continents were first divided in historical time is geologically and physically impossible.
Completely possible in the former nature. You seek to limit the past to the present nature, that is religion and not fact or science.
Man was on Pangaea!! Noah's ark landed on Pangaea. The tower of Babel was built in Pangaea. That is why animals and people could get around as we see has happened! The evidence fits.
