A New Look at the End Times Two Witnesses-- Immortal or mortal? {Preferred Version}

Could the Two Witnesses of Revelation 11 almost be here?
It depends on whether you think the Tribulation "End Times" has started. Using scriptures, some key points are explored about the identity and mission of the Two Witnesses. Are they angelic? Or mortal people? Why are they called Olive Trees and Candlesticks? Who is their main audience going to be? Where are they going to be 'eliminated'? Hopefully these points will cause you to ponder the topic.

Scriptures to explore:
Four horsemen of the Apocalypse: Revelation 6

Main information about the 2 Witnesses comes from Revelation 11: 1-14 and various verses from this are specifically referenced.
