Why do programmers mostly use high-level language rather than a low-level language?

Answer 1

Because high level programming languages are just upgrades of low level ones. They don't have the same flexibility as them but offer many alternatives, workarounds and new features...
Making a basic game in a low level lang would take about 2.000 lines of code while but only 600 in a high level one. Would be better, faster and easier...
(PS : they dont prefer high level ones in my opinion though...)

Answer 2

Just because its much easier and reliable .
