Could the closest star to our Sun, Proxima, have a world with life on it?

Proxima is a red dwarf star with about 11% of the Sun’s mass. With a diameter around 278,280 km’s, it is not much larger than the planet Jupiter’s 142,800 km’s. (Jupiter has only about 1/1,000th of Sol's mass.)

Proxima’s life zone is around .007 AU’s (Mercury is .4 AU’s from our Sun)

A possible Gas Giant, or Brown Dwarf might be orbiting Proxima at around ..17 Au’s.

The scientific consciences is that any terrestrial planet with in this Red Dwarf’s life zone would be tidally locked with one side always facing the star. Of course, this is what they said about Mercury before a probe proved otherwise.

What about a large planet-sized moon orbiting Proxima in or near it’s life zone? If it is just outside the life sine, oceans of water could be tidally heated like with Europa, but there would still be bright sunlight and warmth on the surface.

I think it is possible there could be an Earth-like world in the Proxima system.

But there is another problem. Proxima is a flare star. Could life evolve to survive flare’s. Perhaps the gas giant could shield it moons from flair activity?
