Amino acids are found in interstellar material.
Thus, it is possible, even likely that the “building blocks of life” were here from our solar system’s beginning, or were deposited from asteroid or comet collisions during the early years.
If true for us, probably true for many, if not most star systems in our galaxy.
The entirety of this star system was formed from matter ejected by dying first and second generation stars. It is therefore unnecessary to say amino acids came here from outer space. Everything here came here from outer space.
