Where did first cell come from?
The Cell Theory states:
All living organisms are composed of cells. They may be unicellular or multicellular.
The cell is the basic unit of life.
Cells arise from pre-existing cells.
Lets see which one of you on here is going to try and outsmart modern world biology scientists.

With the little knowledge i have on evolution im guessing a lightning strike in some huge storm caused some reactions with atoms and made a cell which went through a good amount of mitosis and brought about life.

Ok...simplest explanation. Through chemistry and environmental stimuli formed the first simple proteins. Simple protein chains again through environmental stimuli bonded to become somewhat more complex proteins. RNA and DNA enabled the more complex chains to become the first uni-cellular organisms that were "self replicating".
Prokaryotes inhabited the Earth from approximately 3–4 billion years ago.No obvious changes in morphology or cellular organisation occurred in these organisms over the next few billion years.The eukaryotic cells emerged between 1.6 – 2.7 billion years ago. The next major change in cell structure came when bacteria were engulfed by eukaryotic cells, in a cooperative association called endosymbiosis.The engulfed bacteria and the host cell then underwent co-evolution, with the bacteria evolving into either mitochondria or hydrogenosomes. Another engulfment of cyanobacterial-like organisms led to the formation of chloroplasts in algae and plants.

In Darwin’s day,it was believed the cell’s structure was very simple. Ernst Haeckel, Darwin’s popularizer in Germany, claimed that a cell was a ‘simple lump of albuminous combination of carbon.’
But modern science has discovered vast quantities of complex, specific information in even the simplest self-reproducing organism. Mycoplasma genitalium has the smallest known genome of any free-living organism, containing 482 genes comprising 580,000 bases. Of course, these genes are only functional with pre-existing translational and replicating machinery, a cell membrane, etc., so the first cell must have been even more complex.
It is simply not plausible this could have developed spontaneously from lightning striking dirty water.Source(s): http://creation.com/how-simple-can-life-be

NO one knows for sure. Not even you. Science is neither pretentious nor based upon faith. You're free to believe what you want.
