Is it prone to be microbial, extra biologically complex--or even clever? What may this type of discovery suggest for all times the following in the world?

Nevertheless, it is at least suggestive of the idea that it’s fairly easy for a planet to go from simply having organic material to actually having life. If the transition from organic chemistry to biology were difficult, we might expect that it would have required much more time. While we cannot say anything definitively, the early origin of life on Earth makes it reasonable to think that life would emerge just as quickly on other worlds with similar conditions. 2. Three lines of evidence that give us at least some reason to think that biology may be common in the universe.
Notice the period of “backward” motion in the middle of the loop. The white dots in a line just right of center are the planet Uranus, which by coincidence was in the same part of the sky. Photo by Tunc Tezel. The real difficulties for the Greek model came with the planets. Unlike the Sun and Moon, the planets do not move steadily through the constellations. The Sun moves along the ecliptic at a rate of just under 1 degree per day, which is why it takes just a few more than 360 days to circle all the way around.
Rest easy, because I will not tell you that you are wrong. How could I? I’ve spent the entire chapter explaining why, according to current scientific understanding, it is eminently reasonable to think that life could be quite common on worlds that number beyond imagination. And while we haven’t yet discussed the scientific issues that differentiate getting intelligent life and civilizations from just getting life of some kind (that will come in chapters 5 and 9), sheer numbers suggest that if life is very common, civilizations ought to be at least somewhat common.
