Can the absolute value of internal energy be determined ? Why or why not ?

Can the absolute value of internal energy be determined ? Why of why not ?

Can -2 be the absolute value of any rational number?

What is the origin of internal energy of a system? Why cannot absolute value of internal energy be determined?

Assertion :- Absolute value of enthalpy can not be determined. Reason :- Enthalpy is defined as H = E + PV, and value of internal energy can not be determined absolutely therefore absolute value of enthalpy can not be determined.
