The creation of formless matter of earth and gradual evolution of form of earth is referred to in two Holy Verses:
‘’Say: Is it that ye deny Him Who created earth in two days? And do ye join equals with Him? He is the Lord of (all) the Worlds’’ (41:9)
The two days referred in the Holy Verse may be taken as metaphorical; a day in the sight of Allah (SwT) may vary from thousand to thousands of years in our reckoning, as laid down in another Holy Verse:
‘’The angels and the Spirit ascend unto Him in a day, the measure whereof is (as) fifty thousand years (70:4)
While the Holy Verse (41:9) refers to formless matter of earth, the gradual evolution of the form of earth is referred in the Holy Verse following the one noted above:
‘’He set on the (earth) mountains standing firm, high above it, and bestowed blessings on the earth, and measured therein all things to give them nourishment in due proportion, in four Days, in accordance with (the needs of) those who seek (Sustenance)’’ [41:10]
The formless matter assumed form gradually in a measured manner so as provide sustenance on all forms of life of earth. The measured manner had to have precision, thus the mountains were set as high as 29,000 feet above sea level, and then from such heights, it had to be measured to the lowest depths—the very bottom of the oceans, which are 31,600 below sea level. The vertical difference between the highest and lowest points on the solid crust of the earth measures to 11.5 miles. The earth was thus endowed with all that it needed to sustain life, maily water, taken to be elixir of life, on which depends the survival of vegetable and animal life.
