Electrons flow from negative to positive. This IS the actual flow of electrical energy. Current flowing from positive to negative was defined when we didn't know enough about property of electrical energy. In reality, nothing flows positive to negative.
While the cloud base can be either positive or negative, statistically, among most cloud to ground strikes, cloud base is negative. That will cause strike to start from cloud to ground.

I believe there are three types of lightening one comes from the sky and goes down the usual. Another comes from the ground and goes up. The other i think is called spider lightening scatters accross the sky but never comes down.

NO. The excess electrons accumulated in the air produce a differential voltage which discharges to earth in the form of lightening. Kind of like when you accumulate excess electrons by dragging you feet across a rug and then approach a door knob with your finger - ouch! - the "lightening" you create does not come from the door knob.

lightening forms when two electrically opposite objects come closer(clouds), so there will be a potential difference between those two energies, energy transfers from high energy to low, which you see as a lightening, it forms in sky and comes to earth (usually to the highest point.
example:- tall buildings will have a a pole like stuff on the top so the electricity will pass through that pole to earth preventing the building fromdamage.

The actual stroke of lightning usually goes from the ground the the cloud. However, the negative charges from come from the cloud to the ground, then is the actual stroke. For more, visit http://en.wikipedia.org/wiki/Lightning

Yes, it does start from the ground and go up.

I have seen a lot of lightning storms and whenever I see the lightning, it seems to be coming down from the sky, not going up.

yep it goes up and joins with the lightening coming down

No, it comes from outher space. Charged particals fly through space from stars or other things. they always come throught our atmosphere. some times if the air is charged, from friction created in wind, they react causing lightning.

Yes it does. Researchers and scientist experimented, studied and observed this and that is how they know. They showed this on TV and saw it once. I believe you can buy the video from NOVA.
