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.

Astronomers tend to put "potentially habitable" in a very big range. I agree that there are planets that can and most likely do hold other life forms but the amount of things needed in order to be completely habitable is huge. They consider certain distances possibly habitable relative to the sun but we don't know if they have water, ozone layers (considering they are similar to human needs), etc... I do agree that there are many similar Earths out there.
