The series has enough science f... I mean cr... ap. Time travel is something they can't afford with my loyalty to the series as well.
Here's something I did during a sleepless night. Don't ask. I've lost some of the details for math steps within. And it is close to baseless most of the time. Oh well, it was fun at that moment.
[Baseless]
What caught my eye is... the derelict Reaper, that's tens of millions (correct me here) of years old.
Funny thing, it's still nearly identical (or did I fall asleep during the cutscenes?) to the rest of the Reapers.
Given the number of them (say several tens of thousands as per cutscenes), and that they "massively reproduce" every 50 thousand years, and given that the galaxy is ~14 (13.2, but what the heck) billion of years old, that leaves roughly 280 thousand of potentially succesful reproductive cycles.
(Not counting that the galaxy was an unusable heap of mess, so to speak, during its "childhood".)
If it would take around 5 years to fully develop that human reaper (2 years since the death of Shepard + 3 more, based on the visual-completion-degree-that-I-came-up-with from the last boss fight, which was ~40%). So, how many colonists did they use after all? I'm assuming it takes 1 to 2 billion to finish it. They could probably make around 8 from Earth-like planets (in terms of population). Let us use this as the "standard world" just for the sake of some rough numbers.
There's around 40 clusters to explore in both games total. Each of them has around 3 star systems.
Each of them has roughly 1/6 chance it is well populated (1 out of 3 by 2 times for clusters to star systems) by some species (at least on some average I came up with last night).
Assuming THESE planets are all more or less overpopulated in terms of total organic mass, there's 120 star systems with a chance of 0.167 that there's one organic-mass-Earth-equivalent planet for each of them.
(Results in 20 Earth-like planets across explorable ME galaxy. Probably a VERY low estimate, but it depicts the "star mapped" part of the ME world rather very closely.)
Then we adjust for... well... the unknown "terminus systems'n'stuff"... probably two times more star systems we've never heard of. Makes 240 stars at 0.167. Around 40 huge-ass-overpopulated worlds.
Considering that the rest of the galaxy is of no use to the Reapers... around 320 new Reapers per successful cycle, given that they did not exterminate worlds entirely and even "seeded" them to maintain a steady harvest. Also, it might be useful to assume that Reapers deliberately use (and we know they do it) specific Mass Relay positions also to reduce the possiblity of "future crops" to be discovered. Thus maintining a steady harvest rate.
Since the cycle has repeated itself (not taking gradual changes in star layout & whatnot into account) we get around 89.6 million Reapers since the Big Bang, heh.
Kind of A LOT. Sure, there had to be a point where they started small, thus arithmetic progression would be the wrong method, but given this huge number, it suggests either a) there's a lot more than it is shown in the cutscenes or

they were created or appeared a lot later.
Both options also seem probable.
We do not see any more than several tens of thousands at once in the cutscenes (aka the dark space shot), which would suggest they were created around 10 million years ago.
The derelict Reaper (again, if I'm right about its age; can't verify now) with its 10 millions suggests 64 thousand new Reapers, if the 50 thousand year cycles started around the time, when it died.
(I'm not taking exponential growth of Reaper indoctrination capacity. Assuming it is limitless per Reaper, and that only the pace of indoctrinating whole planets is faster with more Reapers around.)
---> So, yeah, they were created.
Tens of millions of years ago.
[/Baseless]
Anyway, I've already forgotten what I was trying to accomplish, but I (for me, at least) concluded that the Reapers have been made around 10-20 million years ago.
But, please, don't ask me how I got those numbers. It was 3 AM and I was just staring at the screen for 2 hours
