Not sure if this has been answered yet but... who is this guaido? What is his history? His policy stance? Why are people treating him like the messiah when only a few weeks ago his was an unknown nobody?
People aren't treating like a messiah they're treating him as the legit interim president of Venezuela. All he has to do is keep the country functioning and get the elections going to install the next president by official channels. His denouncers on the left in the West are convinced he's the devil incarnate and a right wing puppet dictator based on nothing other than he reached out to the US, and other nations, to protect himself against a dictator known for ignoring the law and killing and imprisoning his rivals because he's a dictator but he's a left wing dictator so nothing to worry about people let's let Venezuela sort it out and by sorting out in reality means Gaida won't last 6 weeks.
What we do know is that he comes from a centre left party and light has been shone in his past. There's not much to go on but hardly proof he's as bad as his detractors think he is.
