After years of scientific work he concluded that only living cells can produce other cells, or that only life can produce life.Therefore, if it was somehow proven that cells can be generated from non-living matter, that would disprove his findings.

You are describing the solar nebula theory to a friend. You point out that it provides an explanation for the regular motion in
Goryan [66]

Explanation:

The widely accepted theory which explains the formation of the solar system is known as the Nebular theory of origin.

The Nebular theory states that the solar system is formed by the explosion of the large gaseous clouds in the centre due to various factors which took place around 457 million years ago.

The explosion leads to the formation of the dust particles which accumulated in large amount in the centre and the suspended particles revolved around it and formed the planets and the centre is known as the sun.

The theory can be proved as :

1. the direction of rotation of planetary bodies are in the same around the same direction.

2. The suspended particles formed the disk around the planets.

3. The planets near the Sun are small and possess lass amount of metals and the silicates whereas the planets far away from the Sun-like Jupiter are larger due to the presence of these metals and silicate which attracted the hydrogen and Helium.
