questions about judaism

1 why don't jews sacrifice animals no more? muslims still do that
2 why do they have synagogues now instead of temples?
3 why do they have rabbis now instead of priests?

Some Jews believe the Third Temple will be built in Jerusalem and animal sacrifices will resume so that their meat hungry god can be pleased.  Of course the Muslim temple will need to be demolished first, which will start a major war in the Middle East along with the US.  The thing about religious prophecies is they don't work unless you intentionally follow them.
