Very good question.
My guess is that the Captain of an aircraft occupies the Left seat in the cockpit. That has been tradition for a long time for most all countries. If the passengers were allowed to enter and deplane from the LH side, then the Captain could keep watch on the process. In earlier days, aircraft had propeller engines and these had to be shut down during passenger ingress/egress. It would be easier for the Captain to watch for approaching passengers and shut down the engine(s) on his side of the aircraft.
That brings up the question: Why do cargo aircraft have their doors on the port side? I never asked Why?.

my guess is that aircraft would be best to all arive at the gate in the same orientation to load and unload passengers and cargo to prevent accidents or "crossover" of deplaning passengers and cargo
i have noticed on many of the modern smaller "heavy haulers" the passenger and cargo doors are on the same side (left), passenger door up front (or same as cargo door) and cargo to the rear (pilatus PC-12, gippsland airvan, quest kodiak etc)
smaller GA aircraft have doors all over the place - examples: beechcraft bonanza A-36 and Cessna 206 stationair has double clamshell doors on the right but the piper seneca and piper cheyenne have double gullwing doors on the left
at least some vintage airliners had passenger door on right and cargo on left such as the DC-3 - just noticed this today wilst flying a united airlines DC-3 in my flight sim

FedEx heavy cargo aircraft have the cargo door located on the left(port) side of the a/c. The only reason that I can see for that is it is more convienent to access the a/c from the same side as the crew would deplane.
This brings up the general question: Why do aircraft have the Command Pilot sitting on the LEFT side? If you do much study of the History of Aviation, you will find that even though the Wright Brothers invented the aircraft, they sat on their patent and didn't share it with anyone. It was Europe and specificially France that developed many of the early aircraft design patents and much of the terminology. Every wonder where we got words like aileron, longeron, aerodrome, squadron, etc. I kinda think that those early aircraft designs had something to do with placing the Pilot on the port side.

to answer the question about pilot on the left = most airliners are certified to be flown by two pilots - one pilot acts as pilot-in-command (PIC) but it can be either at any time so pilot-in-command can be either left or right at any phase of flight - the captain traditionally sits on the left but he isn't always pilot-in-command
those are doors used to access an aircraft, like the passenger door on an airliner.
