Life start so easily
How do you know? Organic molecules form quite easily. But there's a long way from that to the DNA -> RNA -> Protein cycle. Having said that, the sheer size of the universe in terms of stars suggests that if life does not start easily we can nevertheless expect there to be lots of it.

So do I, just based on symmetry principles.

On Earth wasn't it 2.5 billion years of single-celled life followed by a billion of multi-celled? That suggests the transition is a difficult one doesn't it?

Yeah - we're here to show the rest of the world how to take a good idea, establish a government around that idea, and corrupt it beyond all semblance of it's original form. Wait - that makes us like - the rest of the world.

I have a question in mind from many days.. are we alone in this universe or we have any neighbour new of far from our planet.. is there any astro scientist here who answer this question :confused::confused:

Warning: I'm not a scientist :) The problem with scientists or humans is they think they have explored all or know every bit of truth starting from big bang(They don't really know how it happened ;P ) We could not explore our universe , we don't know the beginning or end.. Hope we will meet our neighboring planet member's soon or later. Thanks,

No, that's precisely the opposite of the scientific method. You start with the assumption that you don't know anything; you come up with a hypothesis, and then try to disprove it. If enough people fail to disprove it, then it becomes the accepted theory. You use the word "theory" instead of the word "fact" simply because you're not ruling out the possibility that future evidence might shed new light on the matter.

No we are not alone and they have visited us before but they went to a Justin Bieber concert and have moved far away stating there is no intelligent life here on earth.

Actually the transition from Karyotes to Prokaryotes to Eukaryotes was a bigger jump, biologically speaking, than from single celled to multi. The LUCA was probably more closely related to an archaea rather than a bacteria, and was flitting around the oceans some 3.8 billion years ago. Now it is obvious that as this was a prokaryote and didn't just pop into existance it must have evolved from a simpler organism that entered some sort of simple symbiotic relationship so as to form a simple prokaryote. Proof of life extends to about 3.85 BYA, but there is evidence of life from chemical analysis of zircons from 4.4 BYA, thus meaning that life started before the LHB. Some see this as evidence that life started not once, but twice. Intriguing thought that within 100 million years of planetary formation there was life on Earth. If one accepts this theory then one must accept that life is so universally abundant that it will be the norm rather than the exception. Of course one has to factor in other biological, chemical and temporal factors as to how easy it is for intelligent life to evolve, and of course some civilisations could have risen and fallen before even the Earth was formed (Though not long before this, but that is another argument).

Really? That's not what I've observed. Many, if not most, scientists are arrogant and full of themselves. That's what I've seen.
