you read all the time that the marathon is a mostly aerobic event, being xx% aerobic. but how can there be a specific number? for some the marathon is their 2:20h race pace, for others it's 3:30h race pace. Am I not getting something?

Yes, you are missing the fact that overload levels are relative to the individuals capacity, VO2 max and lactate threshold if you like.
A 2:20 and 3:20 are both aerobic the same amount but the 2:20 guy has a much larger aerobic system.
so the 2:20h race pace (19 miles or so) of the 3:20 guy is less aerobic than the 2:20h race pace (26.2 miles) of the 2:20 guy?

This is wrong. Where did you get something like this? An improvement in your aerobic system doesn't just magically reduce the max amount of distance you could race at your aerobic threshold.
The numbers are based on elite runners, but given that you are already at 99% for elite marathoners, not much room to go for those who take longer.
Time spent performing the activity is the correct metric, not distance.
When u hit the wall does it become anaerobic?
No.
The good news is that you might have more to learn about running than you thought and can improve by reading or talking to good coaches.

Hitting the wall is associated with running low on muscle glycogen. Since you cannot "burn" fat (or protein) anaerobically you definitely are not becoming "anaerobic".
Is becoming dehydrated feel the same as glycogen bonking?
The difference in aerobic energy production between a 2:30 marathoner and a 3:30 marathoner is something like 99.0% to 99.2% or some other nonsense.
Pretty much the only time you will be producing energy anaerobically during the marathon is during the first 10s or so (phosphagen system is always turned on during the initial steps of any running pace) and maybe the last minute or so if you can muster a "sprint" (anaerobic glycolysis as your "sprint" is going to be more of a slightly increased speed).

Nonsense. You're not restricted to using just one energy system at a time. You can, and do, use aerobic and anaerobic systems simultaneously tough one may be the dominant energy provider at a particular moment/pace.

Yeah, and at the marathon the aerobic is 99% dominant, idiot.

I never said you were restricted....I was talking about dominant energy systems.
You are always using all three or four if you want to get picky.
Predominant energy system for the first 5-10s of any activity that takes you out of a resting state is phosphagen system. Predominant energy systems for the entire Marathon are aerobic glycolysis and beta oxidation. The percentage of aerobic glycolysis vs beta oxidation depends on training status, nutrition, and how fast you are actually going.
