Exactly. On other planets, if there was life based on other chemicals, totally other conditions may be favorable for the life and thus the life forms will look differently ;)

that is true to some extent, but i think that even with a world made out of Si instead of C, the same principles of evolution would create creatures that might have some common features

to some extend... they will probably feed on something, divide, but I mean their appearence may be totally different ;)

it's not certain for now but most likely yes!
I don't know how I can explain that.I just believe''Somethings's changing,something will be change..''

not necessarily. I mean think of it. It makes sense to concentrate things, for example control (nervous) organs, which will probably wind up in a sort of brain. brains evolved at least twice independently on earth. It makes sense to have a sort of lens organ (eye) that should be placed in the part that first meets the environment. Eyes have evolved at least 6 or 7 times on Earth. If you want to fly a wing-like organ will most likely be the solution, and wings have evolved 3 or 4 times on earth. Etc etc.

On the sacale of the Universe, with finite construction possibilites, it's inevitable that biology is constructed on a planet with the same specifications of the Earth. Which is to say, that the emergence of biology is inevitable and exists through-out the Universe.

1) why do you think, there are finite construction possibilities?
2) why should be the emergence of life inevitable? :lol:

We don't even know if life actually began on the Earth. Some people have suggested that it may have been carried here e.g. along a meteorite or such. Maybe the early Earth wasn't suitable for the beginning of life after all, but instead some other place was?
