First you must bear in mind that the verb SER and ESTAR in Spanish differ from English, where the verb "to be" is used for both cases.
The verb SER it is used to describe appearances, identity, family relationships, when and where an event takes place, time and date.
On the other hand, ESTAR is used to express a mood or health status, an aspect, the marital status of a person, their location.
The ways to conjugate each verb for different people of the present is as follows:
SER:
yo soy
tú eres
él/ella es
nosotros somos
ellos son
ESTAR:
yo estoy
tú estás
él/ella está
nosotros estamos
ellos están
