From the first one?

You seek superiority, not knowledge.

The problem is internal, not external.

NTA but you're right, a bunch of amino acids bumping around isn't going to make a protein, however that's not how biologists think proteins came about. If you think about it, you need DNA to code for information for making proteins, but you also need proteins to replicate DNA (DNA polymerases, helicases, ...etc are all proteins), So which came first, DNA or Protein? the current prevailing theory (although far from being universally accepted) is that RNA gave rise to both DNA and Protein, this is the premise of the RNA world hypothesis
There is evidence for the RNA world hypothesis, for starters, RNA can code information just like DNA, but importantly RNA can also have enzymatic activity just like proteins, these molecules are known as ribozymes, they are basically RNA enzymes. There are many papers which explore the evolution of ribozymes and how ribozymes could very easily evolve into highly efficient self replicating enzymes under the right conditions. Also another thing to mention is that the ribosomes (the molecular machines which synthesize proteins) are mostly made up of RNA, ribosomes are presumably one of the remnants of the RNA world.

The full name is systemic lupus erythematosus (SLE)
It is an autoimmune disease where your immune system attacks normal cells
Is there anything more you want to know?
