It's to show an exception (which is often the purpose of "yet") because in the first clause it identifies an action, then then it's like "but wait, maybe the action didn't really get going" in the second half of the sentence
Answer:
There are many interesting jobs that surprisingly exist. Brain surgery is one of them. I think that people who do brain surgeries are psychopaths because I can't imagine opening a brain myself. This job is both interesting and dangerous because if the doctor touches the wrong part of the brain, the patient will intinctly die. The human brain looks like your intestines, a pinkish jelly-like substance it's VERY sensitive. I wonder how did scientists discovered how the human brain works. How could a insignificant creature learn all by itself how it's brain works? If we could learn about our brain, then why do other animals can't? How did we discover cells? How did we create technology? This is when I start thinking, Do aliens exist? I have done unstoppable research about how did humans discovered or created technology. I have found absolutely nothing that says about that. But I do now know, that the Egyptians had drawings of aliens in their pyramids. So I now think, Did aliens gave us technology?
