I'm going to start this with a saying in Spanish: No comas ansias, Santos.

You do good by playing the devil's advocate in all of this.  Your

Always try to rely on scientific findings for your answers.  And even
then, remember that much of what scientists postulate are theories and
hypothesis.  As a starting point for your research on your first
question, check the following link regarding the Cohanim:
