Wow, what a question!  Unfortunately, I can give no definitive answer.  
The reason being for one, is that the line between human and 
non-human is blurred, and people have different definitions as to 
what is and is not considered human.  Take a look at our partial 
family tree, gleaned from the fossil record thus far: http://www.mnh.si.edu/anthro/humanorigins/ha/a_tree.html
There has been several new discoveries since this chart was made, 
but as there is still controversy as to where they belong in this 
framework, this will have to do for now.
So firstly, when you ask "Who was the first (hu)man?"  we're in a 
quandary.  Are all of the species listed above considered human? 
Does humanity begin with the genus "Homo"?  Do we draw the line 
with the first Archaic Homo sapiens or only include those individuals 
who fit into our own classification of Homo sapiens sapiens? 
	If we draw the line at Homo sapiens sapiens, then the first "Human"  
existed, according to current data, in  Africa and/or Southwest Asia 
around 115,000-96,000 years ago, and would probably have been 
similar looking to the people who live in those places now.  We're not 
sure which of these places, if either, gave rise to the first Homo 
sapiens sapiens, because the fossils from these areas overlap in 
their possible age ranges. 
	To further complicate matters, it is highly unlikely the "first human" 's 
remains are even preserved.  The chances are more likely than not 
that they decomposed, as only a small percentage of life forms 
become fossils.  Long story short, no one knows, or will ever know 
what the first person really looked like because no one can agree on 
what is or is not a human and the fossil record is not complete 
enough to be certain about any guess.  For a much more in depth 
discussion of this subject, check out this website:  http://daphne.palomar.edu/homo2/modern_humans.htm
	Happy hunting!
