Becasue there was no one inventor of the clock.
12 hours of daylight existed (ancient Sumer) about 2,000 years before the modern clock (medieval Europe)
Even when clock were invented, it was hundreds of years before they also showed minutes, and another hundred or so years before they showed seconds.
i was curious and it actually doesn’t look that bad
By 1,500 BCE, Egyptians were using sundials to divide the period of daylight into 12 segments. One explanation for their choice of 12 comes from their recognition there are about 12 lunar cycles (new moon to new moon) per year, which is also the reason most early cultures divided the year into 12 or 13 lunar months of 354 or 384 days.
A more entertaining possibility suggests 12 stemmed from the number of joints on the four (non-thumb) fingers of one hand.

Well now I’m conscious of all the joints in my non-thumb fingers.
Not suuper useful for time though, honestly
Would be nicer if we had an overall base-12 number system
the clock and the AM/PM system makes much more sense when you count from 0.
0am 1am 2am 3am … 11am
0pm 1pm 2pm 3pm … 11pm
instead of:
12am 1am 2am 3am … 11am
12pm 1pm 2pm 3pm … 11pm
the ancient people that invented the clock were programmers all along??
you may find comfort in knowing that in a mathematical sense, they’re the same. this is because 12 hour clocks use modular arithmetic. doing arithmetic modulo 12 is basically the same thing as doing normal arithmetic with the whole numbers, except you add in the rule 12=0. for example, modulo 12, we have 15 = 3 + 12 = 0 + 3 = 3. (this explanation of modular arithmetic comes from viewing it as “normal addition” in a quotient ring.)
this is all a long winded and overly technical way of saying that it’s completely reasonable to say that 0am and 12am are the same thing.
It has nothing to do with French. The decimal digit notation was invented in ancient India, then it got adopted by the Arab world and finally reached Europe in the 10th century. But even before so called Arabic numerals ancient Romans were using decimal system as well and their Roman numerals are also based on decimal system.
Thus people all over the world agree that the decimal system is superior, since the ancient times.
This was one of many things the French fixed with their revolution but was cruelly taken away by the reactionaries. Decimal time
VIII. Each month is divided into three equal parts, of ten days each, which are called décades… The day, from midnight to midnight, is divided into ten parts or hours, each part into ten others, so on until the smallest measurable portion of the duration. The hundredth part of the hour is called decimal minute; the hundredth part of the minute is called decimal second.
Day doesn’t start at 12, it ends at 11:59 before turning back over to 00:00
Personally I’d argue for base 36 time!
36 hours, each consisting of 36 minutes, each consisting of 36 seconds.
Lets you treat time as a 0-Z number with two decimal points, the day ends at Z.ZZ at night, plus base 36 is SUPER conveniently divisible, which jives really well with how most folks actually consider how much time they need to do whatever or what time it is.
