Galaxies Distances

If the Milky Way formed at about the same time as recently discovered
deep space galaxies why are they 12 billion light years apart?

Becuse they formed in different places I would guess. I'm not entirely sure what exactly you mean though.

The Universe started small and expanded I understand but not at 12 billion light years speed?

What do you mean "12 billion light years speed"? The universe has been expanding for 14 billion years .... why can't things be 12 billion lighyears appart?

I understand the universe is speeding up all the time do you know at
what speed it is now?

That, actually, sounds correct. The Light Year (Ly) is only a measure of distance, though it also sounds like a measure of time. I'm not a cosmologist, so I can't comment on whether the 2 are linked in your scenario, but certainly thinking about it does seem to suggest so.

Don't forget disley, as we are currently looking at it, we see those distant galaxies 12 billion Ly away as they were 12 billion years ago. They have sinced moved from their 'last known position', and where they are now can ge guestimated by following whats called 'redshift'. But thats for a different discussion. if we could stand where we are and look out into space 12 billion years ago, most of these galaxies would probably have looked like large, irregularly shaped star clusters against the night sky.
