What would alien life look like?

We will never ever know.
The nearest star system and unexplored planets to our own is over 4 light years away, i.e., over 40 trillion km away.

Star Trek isn't sci fi, it's fantasy

 As I posted before. A sufficiently large 'Nuclear' (Put, put) style orion ship can reach said planets with 80 or so years. (Off top of my head I always confuse whether that's 80 years 'Ship' time or 80 years 'Planet' time)

 IF the American's had built even a modest version of 20 thousand tonns or so AND with the valve and mechanical computers of the day back in the 1950's then launched said giant robot at Alpha Cent. Well we'd be pretty close to receiving telemitry from said giant probe almost today.

Neat, huh?

question to all.

We came out of the water, developed 4 legs for mobility, then only used 2 as we stood up.
Why couldn't we develop a bigger brain whilst running faster on 4 limbs? Too run away faster? (An evolutionary advantage.)

You can only be as intelligent as your environment allows. There is a limit to how intelligent you can be with only 4 legs and no opposable digits.

 Well... you can adadpt other extremities for manipulation. The invaders depicted in Niven/Pournelle's "Footfall" were basically inteligent pachyderms. Little elephants with multi-branching probiscus.

 Pretty sure the "Puppetiers' from same writers effectivly used their 'Mouths' on the end of their 'Heads' as manipulating organs as well.

Life is weird. Alien life is probably even weirder.

Not at work.
