I'm talking about a single celled organism.

It's just too complicated to do at this stage of human knowledge. Assuming you don't cannibalise an existing cell for parts or just copy the DNA/RNA, you'd have to work for decades or even centuries just to build the parts, let alone be able to assemble them into a living call.
To start with you'd need to build the ribosomes (for protein synthesis) and genetic code (to determine what proteins are produced)
Each ribosome usually has at least 4500 nucleotides bound to 55 proteins. You need at the very least a few hundred (a guess), but probably a vast number would be required.
One simple organism that has had it's genome mapped is Haemophilus influenzae. Its genome consists of 1,830,140 base pairs of DNA and contains 1740 genes.
That begins to give you an idea of the scale and complexity of the project.

Well, I wouldn't say it's not possible, but it hasn't happened so far. Some experiments have come amazingly close, though. Cell-like structures hav been formed, but not exactly like a cell because they couldn't reproduce. As to why it hasn't happened yet...well, it was probably very sli odds for it happening in the first place, and for that to repeat itself, the odds are even more against it. Also, we don't know 100% for sure what the exact conditions were like when life first came to be. The cells could have come from space in dust/meteor, or the clay rocks could have catalyzed the reaction needed to produce/reproduce RNA and DNA...I do however think that eventually cells will be created in the lab. Look at how far science has come in the last 50 years, after all...

Because all life is given by God.
Ha YEA right, like someone would actually put all the thought into individual single celled organisms...God, pfft.
I think it's only a matter of time till simple-life is created. It's created all the time in Nature, it's only time before we finally know how to play as Gods in lab-coats.

Research cell biology and organelles and their functions. Combine that with researching the biochemistry of each function and the enzymes necessary for each pathway. You will have lightly touched upon the reason it is not possible.

it is.
years ago scientists experimented with a so-called "primordial broth" which contained nutrients from different sources and they were mixed in ideal temperature, pH and other values - they did succeed in producing single-celled organisms, but the chances of them advancing into something we know as Life, is too remote.

I think is just a matter of time.. they have already created proteins in vitro, the foundaments of living creatures.

Because we don't know how to yet. Whether we ever will is a question. Whether we should, even if we know how to, is an even more important question.

Nature has it's own built in parameters that cannot be crossed.

We can.....ever hear of Dolly the sheep (clone). If you can clone a sheep in a lab, you can do the same for an amoeba.
