This. The assumption that these ETs would appear in the same form as us, or even in the same dimension, shows us how limited our thinking is.
If a lifeform has gone through let's say million times the evolving that we have, wouldn't their consciousness and expression of life have developed probably into something alltogether different.
Maybe even something that we cannot see or hear with just our physical senses or instruments. There are many theories about this if you read on the subject, people being in contact with different species, but explaining that they came from between dimensions from example.
