I have met some aliens, they are teaching in my school
Well the possibility of other life forms existing is ridiculously low, but the space is ridiculously vast, so we can currently neither prove that life exists nor that it does not exist in other planets... However let's firstly define life, what is life? Life in our planet is defined by whether an object has carbon and hydrogen inside them, however, if any other life exists it is almost impossible that they are made of the same forms, they might be made of other chemical elements. There is also the possibility of life existing in other universies (parallel) and other dimensions, i mean we don't know what's out there,you can never be sure...
