The remains of prehistoric man (dating back 7,500 years) were discovered in here. Our guide said that groups of families would live throughout the cave. Snail shells lined the entrance to the cave which made scientists think that perhaps at some point, the ocean was that high, but it was later discovered that the cavemen ate snails they found in the jungle, then put the snail shells at the front of the cave. If any intruder came close, they’d be able to hear the shells being scratched at or stepped on.
