This is something I see black people doing a lot, basically being overly skeptical of scientists and implying they're somewhat incompetent and "don't know as much as they think they do".
You say these things, but then you take advantage of all the things they provided for us, for granted. Your high speed internet, your smartphone, your satellite tv, you get sick and go to the doctor and take their medicine, you have their surgeries, you drive their cars, you eat their artificial and genetically modified foods...I can go on and on.
So when it's convenient you don't question shyt you just start downloading apps and flipping channels without a second thought as to how that shyt actually works. It didn't just drop form the sky thanks to white jesus, scientists created all of it.
And no, they don't know EVERYTHING, but the scientific method is to continue to learn. That's why technology advances, because of that curiosity and that motivation to improve. Unfortunately a lot of nikkas antagonize it with this "You're doing god's work blah blah blah". Yeah well let your ass get sick and on the verge of death, and see if you don't take that medicine a dr. wants to give you to save your life or keep you healthy, that same medicine that was created by scientists.
