Do similar laws of physics throughout the Universe imply that all life must be like life on Earth?
Hi, I’m an eleventh grade physics student and I have a few questions about extraterrestrial life. I have been thinking about this subject for a while, and I have a theory. Since the laws of physics apply to everything in the universe, then wouldn’t the appearence and evolution of life on a space body follow the same pattern throughout the universe as well? For example, people use the phrase “life as we know it”, meaning life with the same properties as life on earth. Wouldn’t all life anywhere have to evolve the same way? Space creatures and monsters as seen in movies, in my opinion, are products of the human imagination, and if extraterrestrial life was ever found, it would include species such as mammals, reptiles, insects, and plants the same as the ones on Earth, and humans as well. Is this theory legitimate? I just think that all life would evolve the same way, and only under earthlike conditions. Thank you for your time. It’s an interesting idea, but I’m afraid I have to disagree
