“Comer” is not the same as in Spanish. The word is a noun, and one use is to refer to a mortal who arrives somewhere. Two examples.
Mr. Johnson, the British Primer Minister, was the first comer (…que llegó primero) to the meeting.
Mr. Sanchez, the Spanish Prime Minister, was the second comer (…que llegó segundo…) to the meeting.
In American English a comer is someone who is new to something or is a beginner. Consider this example:
Every comer to this activity has to learn the basics (todos los principiantes en esta actividad tienen que aprender los básicos).
So, sometimes you are a comer.
