I was watching a (crappy) made for TV movie named SUPERNOVA the other day... and got into a discussion with my BF about it since I was explaining the sun's too tiny to nova, let alone supernova. He was like wth the sun is huuuuuuuuuuge!
Sooooo
That shut him up pretty fast XD
Same thing goes for the sun being "unique".
It's semi rare, but not that rare, there's lots of stars out there similar in size, density, and heat output as the sun.
Consider it this way...
Our sun is one star in a solar system. There are billions of stars in the milky way. There are billions of galaxies as well. The sun itself isn't particularly special, honestly, moreso the fact that our planet just HAPPENS to be at 'just that right distance' from it for its' properties to support liquid water is moderately rare, astrologically speaking.
Of course, even by those standards, the calculation which factors in everything still estimates roughly 3million inhabited planets in the milky way alone, so go figure.
This's with factoring out having the right type of star/sun, the right distance, the right planet type, the right conditions for water to form, the removal of planets that won't actually create life despite the ideal conditions, and those that are too young to support such yet.
So yeah, we're looking at like 0.000001% of planets in the galaxy and still comes out that high.
Why are we special again?
Even if we assume religious overtones of christianity's "god made us!", he still made the angels first on another world before us, so we're not even special there.
