When we first landed on the moon, who was the other guy

The one who stayed in the ship!

It was Michael Collins.

Michael Collins was the one who stayed in the Command Module while Aldrin and Armstrong boarded the LEM and made the descent to the moon's surface. I think that's what you were asking. See

I've studied species turian, asari and batarian.
I'm quite good at genetics (as a subset of biology)
Because I am an expert (which I know is a tautology)

I'm also quite familiar, too, with matters dealing medicine.
I'll diagnose and treat the galaxy's most sickly quarian.
I've cured most deadly plagues that bring populations to their knees....
....to their knees...bees, sees, fees...Got it!
And I've learned to greatly limit the average amount of fertile Krogan seeds!

And he's learned to greatly limit the average amount of fertile Krogan seeds!
And he's learned to greatly limit the average amount of fertile Krogan seeds!
And he's learned to greatly limit the average amount of fertile Krogan-ogan seeds!

My xenoscience studies range from urban to agrarian,
Tuchanka, Illium, Omega, and those far more alien.
In short, in matters turian, asari, and batarian.
I am the very model of a scientist salarian.

He is the very model of a scientist salarian!

I know the numerous details of several species' chemistry,
From elcor to the volus, from evolution to anatomy,
Krogan reproduction, and the dextro-amino acid strains,
Of which turians and quarians form their cells and organs, bones and veins.

Humans are unique with their wide array of gene diversity,
