No, it does make sense. How can you make complex facial movement with hard skin? Even smarter dinosaurs started having mammal-like skin. And feathers
soon later became prominent. Scales are a primitive skin-type for creatures just beginning to leave water. The only purpose in birds scales have today
is for gripping and defense on weak little legs.
But hey, look at humans. Our feet get hard and scale-like with age too. It's grip.
And nails do have use. Tool use! The fatty finger tips are for feelings, but tool use requires nails. Screws, small switches, etc. All require nails.
They are also good for wire work. I've gotten electrocuted sometimes, but not as bad because my nail was touching it. Matter of fact, it barely hurt
because my nails don't have nerves.
Hair is requires for our tiny skull skin to warm the brain. Also, it helps in emotions and facial structures as all that hair moves on a muscle.
It does make sense to assume(contrary to some beliefs)that ET life would take the same well working,bipedal format it took on Earth,it is the most
logical and easiest way for species to become advanced and propagate past there origional environment(thus keeping with the point of evolution-to
Not at all. Why would you evolve bipedal in a heavy environment? And if a gray is 3 ft tall, that indicates a lot of gravity. Also, why even go
bipedal if you can't have a big brain? IF you have scales, it eliminates complex facial movements because the skin can't move as easily. As such,
the brain does not need to be that big to learn facial muscles. big brains are not needed for intelligence. This is purely a human trait with our
emotions. GO to crows, which are just as smart as apes, and you have a brain no bigger then you nail. Yet they can make tools, hunt in packs, and do
all that apes can. So why even have a big brain? And if you don;t have a big brain, why go bipedal?
Not only that, but bipedal is for life forms that have a need to hunt and run. Dinosaurs had it, but apes did not have it until they began to hunt
meat. And then you need to explain upright postures for your aliens. See, upright postures are for bipedal creatures that have a big top load, such as
a brain. But why would you want that on a grey? greys have grey skin, indicating very little sun contact (perhaps, if they exist, why abductions are
common at night). But then if you can't see, why would you want to walk upright? I understand the big eyes then, for seeing in the dark, but a
creature in the dark wouldn't evolve upright because that would be dangerous. There's more time to fall and hurt the brain. of course, that may be
why they are short. But again, why even have a big brain? Their faces are plain and simple, meaning they don't need facially-influenced emotions. And
if they don;t need that, they don;t need big brains. Hence, why walk upright at all? And if it's dark, you can't even see another face to recognize
facial movements, so again, why have a big brain?
On Earth, intelligence comes in many forms. The human form is only good for humans. Yet just look around, and you'll see creatures as diverse from
crows to whales with brains sizes and body types of many kind. So why do you need to look like a human at all? If a crow can count, hunt, make spears,
remember places, learn language, and do simple math with a brain as big as your nails, why do you need a big brain at all? The only reason humans have
a big brain is because we are influenced my social connections and facial movements. We have one of the most advanced faces of all creatures of Earth.
But you can't have that with scales. And not only that, but you can't have that in the dark. So in the end, reptilians and greys are debunked,
because the energy required to get as they look could far easily be used to make something like a crow, only a bit bigger with a brain maybe the size
of an orange. That would create a species so advanced that it could match humanity in all aspects but emotions.
And the most important aspect of humans, imagination, is completely not dependent on brain size. Humans went from cro magnum to homo sapien with
pretty much no brain size change. So the spearhead of human civilization, innovation and imagination, doesn't even need a big brain.
