Now a days we are seeing every where so many science technology like car bike metro train all are invented by humans which before no one wud have thought it will be possible to migrate from one place to another not just by walkin.  There often thunders takin place who thought that its either god or devil  but science proved that  it is nothin but a type of  energy.

this was just an explanation to the above question.there is no perfect definition for ur question.
