Provide definitions/explanations for the following terms: Theory of spontaneous generation (Abiogenesis) and Proteinoids.

(N/A) $1$. Theory of spontaneous generation (Abiogenesis): This theory suggests that life originated from non-living matter in a spontaneous manner. It was a widely held belief in ancient times that living organisms could arise from decaying organic matter.
$2$. Proteinoids: These are thermal polypeptides synthesized by heating a mixture of amino acids at temperatures ranging from $160^{\circ}C$ to $210^{\circ}C$ for several hours. They are considered potential precursors to the first proteins in prebiotic evolution.
