another question!!! during which phase of the birth of the universe were electrons born? these are needed to create matter, and in the wiki article i can see where protons and neutrons came from during baryogenysis, and then nuclei during nucelosynthesys, but where/ when were the electrons formed?

Quick comment:

The word "Electron" was first coined by the Irish Physicist George Johnston Stoney at Galway University in 1874.

Where did electrons come from ?

They came from Galway of course.

Like myself.

I'm not sure but I think electrons came into being at the same time as quarks which I think was right at the start.

When the electronuclear force seperated into the strong and electroweak forces. Before then quarks and an electrons were one single particle.

Insert phrase said by somebody else.

so am i to understand that quarks and electrons are much the same types of particles?i thought quarks made up the baryon particles ( protons,neutrons etc)?

No, they are not the same particles now, but they were while the Nuclear forces were unified ... at least that's how I understand it.
