A Mufti says that the earth existed millions of years prior to man's appearance.

Answer

The Mufti who spoke about millions of years talked drivel. He is influenced by the nonsense which the atheist scientists of the west din into the ears of people. Let us assume that before man's arrival on earth, there was a history of millions of years in this world. Even if this is so, we have absolutely no Islamic evidence for this. We should therefore not make categorical statements without valid proof of the Shariah. What is known as a fact, is that prior to man inhabiting the earth, it (the earth) was the abode of the jinn. Although even today there are jinn on earth, nevertheless, they were in control of the earth before the arrival of man.

Another fact of certitude is that the animals during the initial stage of man's life on earth were extremely huge. We infer this from the fact that Nabi Aadam (alayhis salaam) was about 30 metres tall. So obviously the cattle, horses and wild animals must have been huge.
