The galactic centre has a super massive black hole++, fun for lemmings...but I'd steer away from the bathtub drain myself.

As to god, for me it's a radio frequency ya catch now and again, some places the reception is good, others not so much, regardless though it's out there, I think it's more of a mental image of unity than an actual 'thing'. Sometimes, it's clear, but like a song being played on a radio frequency, ya talk to yer mate about it
'love the line, 'and ya happy with everything', that's so true...'
"uh, that isn't what they are saying in that song, it's 'and the taffy with everything' like a pizza with everything on it but it's sweet..."
'what?!'
"google it, you'll see..."

On aliens, I recall a youtube with michau kakau?(sp?) and he was talking about levels of civilization, and something about if you were 'intergalactic' you'd send a robot to make a factory to make more robots.  Which sat fine in my mind, and then my brain thought, why do they have to be our size, and ya wonder about the sudden introduction of certain bacteria, or mitochondria (and the Eve), or the sideline genetic code instruction set we got a short time ago and yet shouldn't have as it is outside ancestry models, and ya come to the idea(not really a conclusion) that they have been here since go. something in everything and everyone and totally overlooked as we point our telescopes up wondering 'where are they?'

yeah, alien to me, means non-human, which also goes non-biped, etc etc etc...

If a cell is a living thing, and two is a more, and 1 billion is a fractional amount on a teaspoon, what do they sell to make rent?
