Something the size of a Tyrannosaurus Rex, perhaps, although requiring the addition of a large tail for improved balance? It would have to take into account the size and weight of the bones, how much blood they can produce, the amount of energy they take to move, how much weight they can carry, how much weight the cartilage connecting the bones can handle, warm blood versus cold blood considerations, and so on. At a certain point, larger creatures have to make their way back into the ocean so that their bodies can be partially supported by the water. Maybe a larger creature on another planet might also be able to support themselves with large helium or hydrogen balloon structures. Those would probably be too delicate, though.
You're right, though. Up to the point where an alien becomes intelligent enough to purposely modify their own genetics or work their way around fundamental laws of physics, they would be limited in their evolution by the same laws of physics that have limited us. Gravity, water viscosity and temperature responses, heat transfer, electrical conductivity of organic material, oxygen permeability in cell membranes, etc.
Something or someone is playing games with us,a deception,a charade and whatever or whoever is doing it,
I very carefully and thoroughly looked up definitions of the words paradox and dilemma and what they mean,before using them in this threads headline and they fit fine and very nicely into this threads meaning and i think they are more intelligent and mature than the 3rd grade level words i could have used in their place...

There have also been very small UFO's spotted.
You have to keep in mind that most UFO sightings are something that can be explained. Some however are mind baffling.
So to say that there is a major paradox is not the correct wording. But maybe scientist are spot on when looking for planets like ours to support life.Maybe the aliens are doing the same thing.
I think we are very close to the truth and what you said > "entities from another dimension that show us what we want to see" is just about how i feel exactly,which is what i meant when i said > "Something or someone is playing games with us,a deception,a charade and whatever or whoever is doing it,is making sure that the ufo's,flying saucers and aliens we see and encounter are always nicely fit into our humanly acceptable and human friendly size range...Why?"...

Some good questions!
If they were 1" tall they could already be here without us really noticing them.
If they were 5 miles tall I don't think that the Earths gravity would allow them to keep standing.
I personally think we are being played by entities from another dimension that show us what we want to see.
Maybe they are just from another country.
I know that all the aliens I've seen are about 5' to 5'8" tall, and there are usually 15 of them packed into the back of a 1982 pick-up truck, which is also about 15' long. Coincidence?
