The theory is a cave man banged 2 rocks together and it sparked onto some brush and presto they discovered fire.
The early men found fire by striking two hard stones together hardly . If the fire is not lit at that particular moment the you do it for more consecutive times
They (early man) discover fire using two hard stones.If the fire is not lit they will continue doing that for( 3,4 days).That is how man discover fire.
