Is this an OK question?
Isaiah 40:12 Who hath measured the waters in the hollow of his hand, and meted out heaven with the span, and comprehended the dust of the earth in a measure, and weighed the mountains in scales, and the hills in a balance?
Have read somewhere, can't find where, that if the earths amount of water was only slightly more, "slightly" relative to the amount that exists, life as we know it could not exist. Believe it was 3-4 meters. This because the oceans would absorb too much CO2 and nitrogen.
In light of the fine-tuning of the universe I was wondering if this is a valid point.
This is highly scientific, but interesting in the light of an ordered universe and ecosystem.
