What if Europa were in the habitable zone?

I don't know that much about astrophysics but from what they say about Jupiter's moon, Europa, the 6th moon from Jupiter. It is said to have plenty of water miles deep.
If only Europa were in our own goldilocks zone. It turns out our habitable zone may not be the same zone it was in the beginning of the planetary formation and the late heavy bombardment phase.
I believe also that both Venus and Mars could have developed life but due to mass, exact location and cometary impacts it was more a luck of the draw so by now at this moment in time, Earth won the life lottery.
Since oxygen is a key marker for microorganisms that use photo synthesis from bacteria onward into a vast diversity of potential life, they are looking for these oxygen markers. The fact is, without plants on Earth, oxygen would not exist and life as we know it would not be.
Basically the Earth is only one third the age of the entire universe. The universe itself is about 12 billion years old. So planets that exist out there in their own habitable zones would possibly be millions to billions of years more advanced than ours on planet Earth.

Evolution is still a theory. I do believe that species adapt but they develop primarily in areas that are condusive to their particular formation. So do we come from apes? If so, wouldn't apes have evolved by now into humans? Life, as science has pointed out had to evolve from microscopic origins but this was all God's plan from the begining. That is what I believe. As for human evolution, science proves that Homoerectus and Cro magnon and Neanderthal were here before modern man and that man developed a larger cranium and thus a larger brain and therefore, higher intelligence.

@gullver , The thing is, as missing llinks that never are found is likely because there is no missing link. The ape is a different variant of mamal yet similar in DNA to human, co-existed throughout time, yet lived in various different parts of earth, in all likelihood before the super continent Pangea got ripped apart by plate techtonics. Essentially we all eat the same foods, drink the same water and breath the same air. In many cases all life forms share a common bond and that bond is the planet itself. Also most living and breathing beings on Earth are Bilateral Symmetry:
Read more about animal characterization based on body symmetry in the Boundless open textbook.

@lookatdesktop but there are a lot of scientists refuse this theory
thousands of scientists refuse it.
let me ask you a simple question
evolution from type to type requires a lot of changes, each change produce different creature not completely but there are differences,and there are millions of excavations from both apes and modern humans, and the creatures (links) which were between those two stages, those links should be thousands or millions but there are not a lot of excavations of those links.

Perhaps a different form of life would have evolved but not human. This is what most astrobiologists theorize. That is why the Kepler mission is all about finding life on exoplanets that are based on the life support properties of other worlds far far away in their own unique solar systems.

There is a lot we don't know yet about the universe. But if we keep on pushing forward, one day we will know much more. I am sure not in our lifetimes. We are still in the prehistoric age I feel. And I also believe we could have been way more advanced is we just weren't so greedy as a country.

@lookatdesktop I know. That is part of the problem with moving forward. There are too many entities pulling from all angles. I bet that science is pretty spot on with things, over religion and politics.

@inertia4 Science uses cause and effect, math, laws of physics, motion, mechanics, chemistry and so on. Yes. Science trumps all other forms of thought. But from my point of view, God made the universe because without intelligent plans put forth before anything can happen the universe would be without meaning. There is much cause and effect in the universe and I think God is pleased with his grand design but does man fit into this grand design? If we do then those planets way out yonder are our future destination.

Politics and science don't mix well and neither does science and most religion. For that matter nor does politics and religion. lol

That is interesting about Europa. Many years ago, I read how one of Jupiter's moons named Titan was thought by Scientists (through study) to have possibilities of being able to support life.

Here is some interesting information for you about Titan. enjoy.
All that space and not a single ounce of air to spare. lol
Titan is the largest moon of Saturn and the second largest moon in the solar system. Titan is the only moon wrapped in a thick atmosphere.

Of course, this is just my own form of speculation. There is certainly a lot of grey area in all of this, not dark matter but grey. lol
