(The same argument may be used against the existence of prehistoric creatures in Loch Ness or Lake Champlain: considering that both lakes were covered by glaciers during the last Ice Age, and that glaciers were in fact responsible for helping to carve out the distinctive shape of both bodies of water, any large animal living in either location today would have had to have entered from elsewhere within the last 10,000 years.)
