Galileo observed them around the year 1612.
However, it seems that others had done the same, a year or so earlier.
Also it seems the Chinese astronomer Gan De recorded seeing sunspots
as early as 364 BC.
So, the answer is: probably at least as early as 364 BC. Then they were "rediscovered ", with the new invention of the telescope, around 1611.
The first surviving record of sunspot observation is by the 4th century BC Chinese astronomer Gan De, though he didn't "create a powerful telescope" ... or any telescope at all, for that matter; those came around 2000 years later. So I guess the answer is "no one."
A lot of people seem to believe the answer is Galileo Galilei, but there are literally centuries of recorded observations of sunspots before Galileo's in both Chinese and Western astronomical records. It's possible that Galileo may have been one of the first to realize that he was literally seeing spots on the Sun itself and not something passing between the Sun and the Earth (some of the earlier observers seem to have thought they were planetary transits of the Sun), but he certainly wasn't the first person to observe and record them.
Gallalao was the first to see sunspots.He was blind when he saw them.
The sun has been there for as long as people can remember. So the very first humans were the first to see it.
Galileo was. Fortunately for him, his telescope was of very poor quality, so he was
able to observe them without instantly and permanently losing his eyesight.
