What is this Red Heifer?

We keep hearing about the expectation of this red heifer. What is this red heifer and where does it come from? It is in one place in scripture, but connected with the end time sacrificial system supposed to revise. What sacrificial system? From God? Most of our modern eschatology comes from the Scofield footnotes after the Zionists got to him. But I now question those conclusions and feel it supports an agenda. Could I be wrong? Possibly. Give a listen see what you think. Ill present my case against the red heifer, Third Temple, sacrificial system revision, and dispensational view. Maybe you don't agree.
