Helium is a noble gas. It forms no bonds and is unable to produce even a simple molecule, let along the complex ones needed for life.

Assuming non terrestrial life needs complex molecules. Which we can't know for sure.
When you think about it honestly, we really don't know anything about anything. We don't know how many planets there are in the galaxy (nor in the universe, nor in the multiverse, nor if there is a multiverse). We don't know what the chances are of a given planet being habitable (nor what "habitable (for all possible life)" means, nor what "all possible life" means). And we don't know what the chances are of life existing on a given habitable planet. So apart from the fact that all of the above probabilities may well be at or near zero, we're barely even capable of articulating the necessary questions, let alone searching for answers.
No, we really can know for sure.
Don't be so open-minded about extra-terrestrial life that your brain falls out.
Life needs energy to be moving around, without energy exchanges, by very definition, nothing interesting happens.
An inert element, for that reason is just not suitable for life. It's not a reasoning based on anthropocentricity it's just basic chemistry and mathematics. If things can't assemble together, and combine, and form more complex structures, you can't get life. If you could get life out of simple basic atoms, we would see life everywhere, and we would be creating it everyday in labs. We don't.
Doesnt mean life can't exist there by using other elements, but detecting helium is not increasing the likelihood of finding life there at the very least.
