Maybe they're wrong then.

This counterargument to the idea of unguided evolution depends on an inability to imagine the scale of the experiments involved. It suggests that some lab somewhere by now must have repeated the exact chemical conditions for the creation of recombinant DNA. But such a lab would have to itself be the size of a planet, and allowed to churn for at least a few million years to replicate the random combinations.
There is a large effort among many scientists to figure out just what the early conditions were. This isn't that easy to do--that's at least 2 billion years of time to cross by dint of various deductions.
That said, there have been artificial self-organizing systems made in chemistry labs--that is, molecules which, when placed in a soup of the appropriate raw ingredients, manage to turn out copy after copy of themselves. This is a long way from making cells--it's more like making viruses (which has also been done).
The problem with making more complex things like cells is that all of the layers of structure probably result from the spontaneous self-modification of reactions placed in a sequence of environments each of which is, to say the least, difficult to reconstruct.

I won't say that I know life actually was a fortunate combination of molecules, because we lack the means to prove it. It might have been all evolution, it might have been some all-powerful God, it might have been a combination of the two, hell, it might have been something else entirely. But the fact that we have not been able to recreate it doesn't disprove evolution. The conditions that first spawned life may have been very different from anything we are able to reproduce. Or organic material may have come here via some sort of asteroid collision, giving the planet a limited amount of organic material, all of which is currently...well, organic, or living. Perhaps one day in the future we will be able to create life. Just because we haven't yet, it doesn't mean that we never will, or that it's impossible. There are plenty of things we haven't done yet, that we might accomplish, one day. There are billions of possibilities, and we just don't know enough to say with certainty that any one of them is/was the case.

Problem is, all the possible "unfortunate" combinations of molecules. The building blocks of life - amino acids - are very easy to create, just combine organic molecules and a little energy. We haven't figured out the trick to creating a living cell yet, but we haven't been working on it for that long, either.

They will be able to create it someday but it's very complicated. Keep hanging out here on earth and you'll see it replicated in about 50 years, I bet!

Scientists have been able to create amino acids and protiens from just basic elements, pressure, and elctrolisis.... amino acids and protiens are the building blocks of all organic beings...

Check your science book. Single celled life forms have been created in the lab.

Because life did not evolve in a laboratory in a couple decades. It evolved in a very complex environment over millions of years.

The bible talks about talking snakes and 900 year old men...It's not as simple as you want to make it sound. Try reading some books on evolution before you ask silly questions.

humans have not been able to do alot of things YET. We learn and build on past knowledge all the time. Someday we will find the way.

We can't create any matter in a lab.
Guess nothing exists.
