The islands of Masbate were formed out of volcanic rocks over one hundred million years before man made his appearance in the tropical regions of the earth. Humans then made tools of stone, bone, and wood. Some of these very early stone stools and bones have been found in Masbate.

Village settling grew from the development of farming, pottery flourished, stone tools were improved, and the early Masbate farmers made axes of polished stones. Many stones axes of this kind have been found in Masbate. They are the remains of the first farmers who used the axes to cut down trees. The early farmers also made beautiful ornaments of shells. They buried their dead in burial caves and jars. Two large caves in Masbate, the Bat-ongan Cave in Mandaon and the Kalanay Cave in Aroroy, are known worldwide as burial caves.
