I think there could be – but very basic and not advanced organisms. When we look for life on other planets (exoplanets) we look for very basic building blocks of life that we have evolved from an example being amino acids – we use telescopes to try and dissect the planets atompheres to see if we can find any traces of these cells. We’ve not found anything yet but there is an equation that tells us the probability of finding ‘aliens’ called the ‘Drake Equation’.
