Great, so it would be post flood, cause they probably didn't eat meat before.
Not really. If a flood washes away a fossil we would find it downstream or wherever.
There are no remains of pre flood man or animal, except for some creeping thing fossils and etc.
One should know what to look for and what actually should be seen.
If man and lions and birds and etc etc were here as long as trilobites and other early fossils,
there should be some remains IF they left remains.
No ..... it would be 'pre flood'
Concerning THEIR 'diet' (?) I wouldn't know (of-course!!)
and any guessing, would simply be presumptious, in the absence of evidence
In a global flood, topsoil and mountain sides would be scoured clean, into the seas
~no longer to see the air or the light
Those persons that did not live on mountain tops would be washed away with the silt
Those that remained, would become fishermen or, perish
Maybe, one reason we do not FIND readily accessible PROOF, is because such 'proof'
is at the bottom of the oceans and seas
and it is only when seismic activity, raises, previous ocean floors above sea level, that these strata become accessible
The tools were "found in sediment" ... and so, they were made
PRE FLOOD
and, buried by it (?)
Therefore I reason, that the 'more modern' landmasses, have likely been scoured clean
and while some of the evidence has been 'reworked', via subduction, the remainder
remains as yet undiscovered

The ancient city of Lord Krishna was once thought to be merely a myth
but ruins discovered in 2000 seem to be breathing life into the old Indian tale.
The story goes that Lord Krishna had a magnificent city which was made up of 70,000 palaces
made of gold, silver, and various other precious metals.
The city was prosperous however upon Lord Krishna’s death Dwarka supposedly sank into the sea.
The ruins are situated 131 feet beneath the ocean surface in the bay of modern-day Dwarka,
one of the seven oldest cities in India.
Acoustic studies have shown the ruins to be amazingly geometric, stunning experts.
Many artefacts have been recovered from the site
but perhaps none more important, than one which was dated to 7500 BCE,
supporting the theory that the ruins may well be the ancient Dwarka.
add 2,000 years and we see 9,500 years ago ....
and how many years would monkey man need to learn such skills ???
Denial of the truth.... it happens

It doesn't make it false
