IWhat to watch for

Creer is regular in the present, like comer: creo, crees, cree, creemos, creéis, creen. The stem ends in e, so several forms have a double e — crees, cree, creemos — and vosotros carries an accent: creéis.

Creo que + indicative states an opinion (creo que tienes razón); no creo que takes the subjunctive. Creer a alguien is to believe a person, creer en to believe in something or someone: no le creo, ¿crees en los fantasmas?
