Looking back, about 8000 million years ago (mya), this Earth was only a blazing ball of fire; 4000 mya, it consisted of molten lava and volcanoes; 340 mya life existed only in water; 223 mya land appeared as Gondwanaland; 70 mya birds and mammals appeared; one mya human beings appeared on the scene… We should not assume that we have come to an end of this evolutionary ladder. Through physical metamorphosis and psychic transmutations, we seem to continue to move on.
