if the big bang did in fact start the beginning of the universe, then that means that everything in the universe must be composed of the same elements. Meaning if we did find other planets they would all be similar to earth. And for a planet to sustain life it must be at a correct distance from the sun, meaning all planets with life must be very similar, or even exactly like that of the earth. Obviously the shape / size of the land might be different or the planet might be all water/ land. Does this also mean we've discovered all elements that can exist (excluding synthetic elements) as we've completed the periodic table.
I'd like your opinion on this

[Karakawe]

This is fundamentally correct. According to our current understanding, all matter is composed of atoms, and atoms work in a certain, prescribed way, which we more or less understand (to a point -- utter randomness aside).
The part about other planets being hospitable to life is interesting. The scenario has given rise to many theories on evolution (at least of carbon-based life): if the two planets are considerably similar, it would be reasonable to think that organic material came about similarly (either with the crazy volcanic activity and lightning theory or the one with frozen water). Since evolution from that point was (in theory) so widespread, global, it is also reasonable to assume that the process would repeat in a similar manner on an earth-like planet-scenario.

Thus, the stereotypical alien with humanoid form and elongated head is justified. Amen.

but it makes sense doesn't it. If the planet is too close to its sun, it becomes a volcanic planet. If a planet is too far away it also does not sustain life, which means that life cannot exist in extreme hot or cold temperatures, so all life forms are restricted to moderate temperatures, meaning the planet MUST be a correct distance from its sun. And under those specific conditions, life begins, like here on earth.
What I'm saying is, on a hot planet, the conditions create volcanoes, lava and no life. An ice planet creates snow, ice storms and no life (unless frozen under water), but a planet like earth creates life, like trees and animals and humans as we're all made of the same elements.

kind of depressing isn't it? That MAYBE every habitable planet is very similar to Earth

[Karakawe]

Not too depressing -- the alternative would be that Earth is the only hospitable planet toward life. Life on the other planets might branch out similarly to life on Earth, but that only accounts for earthlike planetary setups and life as we know it. Ever see/read Andromeda Strain?

Ok but what made the big bang and what made what made the big bang.
I personally think that the human mind can't comprehend any thing before time. Therefore we can't comprehend what happened before the big bang.

[Majjikelkitty]

I think that there are so many ways that people say that the universe was created, its only our own judgement that we feel comfortable in saying how the world was created.

[zackary]

why did the universe have to be created?
why couldnt it have just ALWAYS existed? time is only a factor on earth where we use it.
in space it could be infinite.

Not everything is composed by atoms E.G Dark matter is composed from a hypothetical entity called axions which aren't affected by photons unlike atoms.

Everything in science that has happened, will happen again.
So the Big Bang, has happened many times before so we have lots of universes..
So something was before the Big Bang.

My opinion is that I concur. Life must be carbon/water based and must only exist in very specific conditions.

Also what I think you are also implying is that because the universe is so huge, it's mathematically impossible for there to not be other life similar to us, and I also concur.
