Didn't scientists do experiments where they replicated the conditions of early earth and were able to form basic forms of life?

Yes, the Miller-Urey experiment, were they used a mixture of Water, Methane, Ammonia and Hydrogen, connected to two flasks, one simulating the evaporating atmosphere and another containing a pair of electrodes which were stimulated in constant time intervals with sparks, simulating the constant lightning storms of the early earth. 

After a few weeks, carbon based molecules began to form, some aminoacids like Glycine, Alanine and Lysine; Sugars, non-polar liquid solvents such as acetone, and most important, the appearance of Guanidosine and Adenosine (which are the isolated forms of the nucleic bases, Guanidine and Adenine).

Yeah thats the one!!

I am surprised how less people know about this experiment, I only found out a few months ago!

It really is a breakthrough of sorts.

I thought is was  very well known yet it only produces some of the building blocks and only works in labs where man can guide the process. A dead cell has everything you need to build a cell so the real problem is to put Humpy Dumpy back together again. That's the real problem as even if earth is full of these building blocks (just like today with all the dead cells on the planet) the  laws of nature destroys them very fast before anything can be created by them.  In fact on a good day your DNA in each of your cells has to be repaired  millions of time by these protein machines. If these machines can't repair them fast enough (which will eventually happen) that cell will die or worst become cancer.
