How will humanity first discover ET Life?
Best guess: Biosignatures
Most rocky, temperate real estate in our Galaxy seems to be around M dwarfs
If those worlds are habitable, JWST could detect biosignatures in the next decade
If these worlds are not habitable, 
HabEx/LUVOIR may detect biosignatures in more distant exoplanets in the next 2-3 decades
