I made my first Marsey. I used MS Paint and PPT lol

yeah. its actually really easy to copy things from paint to ppt and then use all the rotation, layers, scaling, shadow, etc features in ppt. but it's easier to draw and crop and color and stuff in paint. you don't even need to save intermediate steps, just select whatever and copy back and forth

This neighbor has never done ghetto image editing in powerpoint.

It's actually pretty convenient for super simple stuff because stuff you add in PPT is vector based and if you're familiar with any MS Office interfaces, then your tools are all in the same place. I did that a lot as a student when I needed to just make some quick presentation slides because I could usually get it done faster than GIMP would open.
