There is potentially over 8 [b]billion[/b] planets capable of life in [b][i]our galaxy.[/i][/b]
[quote] By extrapolating Kepler’s findings, astronomers have come up with some not-altogether-unfounded estimates for these values. For instance, they concluded that about 22% of Sun-like stars has at least one planet we class as potentially habitable. Doing the math based on the latest estimates for the total number of stars in the Milky Way, that gives us a rough figure of 8.8 billion potentially habitable planets in the Milky Way. That’s a lot of rolls of the dice, assuming you believe life has any chance at all of starting spontaneously. [/quote]
That's just our galaxy people. There's hundreds of billions of galaxies in our universe. That's a lot of potential for life. We're not special snowflakes.

What if a liquid COMPLETELY different from water supported life on a planet? H20 supports life on earth but on an alien planet liquid diamonds could support life (due to its carbon quantity.) Combustion reactions inside of us cause us to emit CO2, so what if in them they use CO2 (like planets) and derive the C from the diamonds and the O from the atmosphere.
