One of my toenails has come off due to infection, but now my body is replacing that nail with another one of the exact size and shape as the one I have lost. If I have got such a potency to create, then what to speak of the Supreme Living Being lord Sri Krsna. If the sub-living entities can produce so much chemicals then what to speak of the Supreme living entity. This is called inconceivable potency. The living being has got an inconceivable potency to create. I do not know how my nail is coming. And the Supreme Living Entity or God, has got unlimited potency to create. I do not think that any reasonable intelligent man or scientist can deny. Aham sarvasya prabhavo, I am the source of everything, [Bg. 10.8].
