Just because we haven't found them yet, that doesn't mean they are not out there. I cannot remember which astrophysicist said it, but the recent estimated probability of having earth-like planet just in the Milky Way itself is approximately 100 billion planets.

Seems like a random process, that various bits of matter around the sun gravitated to where they would based on their kinetic energy and chance.

One wonders if Venus will change dramatically as the sun cools (well, of course it will) over the next billlion or two years and become much more amenable to life. I mean we know the earth was a red hot ball of lava at one time.

The sun will expand to Red giant stage before cooling. The result for the terrestrial planets, especially Venus will be destruction. Even if it's core remains extant it's atmosphere will be boiled off into space. Along with Earths and Mars etc. So no. It will not become amenable to life after the sun passes thru it's red giant stage and starts to become a white dwarf.

Hmm. Whatayaknow. I would have thought it would gradually cool slightly owing to gradual diminishment of fuel, before the red giant phase, that is.

But this bit from wikipedia states just the opposite:

In fact, even during its current life in the main sequence, the Sun is gradually becoming more luminous (about 10% every 1 billion years), and its surface temperature is slowly rising. The Sun used to be fainter in the past, which is possibly the reason why life on Earth has only existed for about 1 billion years on land. The increase in solar temperatures is such that already in about a billion years, the surface of the Earth will become too hot for liquid water to exist, ending all terrestrial life.

Carl Sagan missed his time. I think he really would have been thrilled with this.

Interesting concept - the heat source getting hotter.

Pffffft-pffffffft, coff, pfffft, It's like you know, the stars are like little atoms an, an, and, the planets are like little electrons.

I doubt that effect moves fast enough for us to ever notice. 3 to 4 hundred years is next to nothing in this equation.
