According to The Bible, the genealogy of Moses, back as far as Abraham is:
Abraham - lived 175 years
Isaac - lived 180 years
Jacob - lived 147 years
Levi - lived 137 years
Kohath -lived 133 years
Amram - lived 137 years
Moses - lived 120 years
Assuming that Moses is literally the grandson of Kohath, who accompanied Jacob to Egypt, and even assuming the patriarchs really lived to improbably great ages, the genealogy requires Moses to have died at least 40 years before the Exodus. The alternative, if Moses was a real, historical person, is that the genealogy is in some way inaccurate.
Aaron is the brother of Moses.
Aaron was Moses' brother.
Moses is older than Aaron.
Yes Aaron was the spokesperson for Moses, as Moses used to stutter.
Tracing a family tree requires documentation of the birth, marriage and children of individuals. Such documentation does not exist in unbroken line back to Moses, not even for prominent families such as ruling dynasties and scholars. Therefore it is impossible to trace your family tree to Moses.
The father of moses was Amram , the brother of Moses was Aaron.
No, Aaron Moses was not his biological brother.
Moses is older than Aaron.
Aaron was older than Moses.
Aaron was Moses's brother and the first high priest of the children of Israel.
