Green men in silver suit, maybe not. Other life - very likely. You can’t prove a negative in an undefined space. We don’t even know everything on land on this planet. Certainly don’t know everything under the water. To say we know something is not out in space...?
Oh I fully believe there is other planets out there in the universe with life on them. No doubt in the millions upon billions of stars out there that there’s another planet with similar life forms. Which is my point.
see let’s say for sake of this argument that the universe was all created in a Big Bang moment. All starting at the same point. Now the theory of universal evolution states that all life and everything else in the universe evolved from that point on, therefore, if bacteria evolved into life forms that later evolved into humans over the course of billions of years, then that also happened on similar planets right? Which therefore means that any other “human like” or intellectual beings evolved at the same pace we did. We don’t have inter-solar system/planetary travel that defies the basic laws of physics which means neither does any other life form on another planet.
