How we realize the man of the planets is similar or about similar to Earth's man:
The meteorites falling on Earth especially in its early time of formation ... these meteoritic pieces were the previous planets of the previous solar system.. that previous solar system was inhabited by various forms of life like our solar system.. then when the previous Doomsday occurred, its planets were broken up into many pieces.. some of these pieces fell on our Earth in its early formation... and they became the mountains of our Earth, and they carried the seed of life to our Earth.
The meteorites which carried the seed of life to our Earth
came from four planets that were destroyed in the previous Doomsday.. for this reason you see the diversity of life forms on Earth, including also the four human races: each race might have come from one or more planets.
Therefore, we see, e.g. the life forms of Australia differ so much from other parts of the Earth.
It may be
the same life forms were carried to the rest of the planets, like Earth in this respect.. i.e. it may be the pieces of the previous planets fell also on the rest of the present planets, and so the life forms will be similar or about similar to the life forms on our Earth ... with some diversity: like the difference between the black, the yellow, the red and the white human races and the difference between the animals and plants of America, Africa, Asia, Australia ... etc.
God is the All-Knowing.
Life is transmittable (or migrant)
The interpreter of the Quran and the Bible told me: it may be
a winged human race may be created on the planets including so many mountains; such man use such wings to avoid the danger of falling from high places, like the hen when it falls from a high place it uses its wings so that it will not be hurt by the fall... for this reason, some angels are winged having two wings like birds or four wings like butterflies.
Because the angels are souls or spiritual beings and were human beings in their material life then when they died they became the angels.
