If our solar system had 2 suns like depicted in Star Wars on Tatooine, would life be possible or would this be too much radiation to sustain life as we know it?

Meaning humans wouldn’t be as we are, or plants, animals, etc would be different? I know we haven’t found life elsewhere in the universe, yet, but it seems that situation would be difficult. And if it’s possible to sustain life with two suns, how?

It's totally doable.

For instance, if the two suns are in a close orbit, they basically just feel like one big sun, and you can have a nice stable orbit without huge variations in temperature. If they're both about as bright as our Sun, you'd just need to be a bit further away so that the temperature is okay. Or, the stars could just be a bit dimmer than our Sun, and the planet could be closer (or vice versa). All you're doing is moving the habitable zone in and out, but if there's a planet there, you can have liquid water and Earth-like life.

Alternately, your planet could be in a close orbit around one sun, and that planet-sun system is orbited by (or orbits) a second sun. If the second sun is dim enough or far enough away, you'll be dominated by the nearby sun, and you again won't get extreme variations in temperature, and you could still have Earth-like life with liquid water.
