fire is natural... wheel is not a discovery but just came from common sense
it is electricity, unless you have to chase for a lightning

the wheel is an invention invented around 4th millenium BC, that's why its in the polls, cause its an invention nonetheless..

if i have to add one invention there it would be one of india's greatest contribution to the world.. 'the number zero 0' ,its actually quite important in trading, computer language & electronics..

na discover ba na nga natural phenomena man na? One of the four elements of nature sa karaan pa. kauban sa Earth Wind Water Fire. Wala na na discover

Ang pasabot tingai niya kay na discover sa humans unsaon pag gamit ang FIRE.

He has a point... Without the humans discovering the benefits of fire & heat, wala pod cguro ni exist kanang tanan naa sa poll.
