There are good reasons for skepticism. Conditions For Life Are Specific And Rare. Beyond a certain degree of heat, organized matter simply disintegrates, and most of the heavenly bodies are far too hot for life in any conceivable form to exist. Beyond a certain degree of cold, no activity is possible since matter congeals into frozen immobility, and many of the heavenly bodies are far too cold for life anything like ours to exist. Life requires a certain atmosphere, and the nature of an atmosphere is determined by the size of the planet it surrounds.
Life requires water and several other specific elements.
It repeated what I had concluded from my earlier reading. That's a technical expression meaning it can't be on a collision course with an asteroid or comet or another planet. . . . Next, the planet has to be cool, which means it can't be too close to the star, so its crust can solidify. Any planet forming near enough to a star to avoid becoming frozen is also too near to contain carbon, nitrogen, or water. These chemicals seem to be necessary for life, and all of them would have been vaporized by a young, hot star.
