Fire!!

Yo!

Fire the only source of heat in the old times. How they found of fire I don't know actually,how was is discovered?

So fire you know the hot stuff that burns things.

I imagine that lightning struck a tree and then it came to be but I highly doubt that early man would go near a burning tree. So maybe they actually found out the secret to fire by evolution because face it a tree struck with lightning is logical, but people of those times and unknown things don't mix.

But fire has really helped our race evolve to what we are right now. From cooking food and lighting our surroundings to smiting and other useful things. Well it has been good but everything has a flip side.It causes mass destruction when not contained. Forest fires are scary as heck.
