Yes, by all means, identify myths and blind beliefs and wishful thinking where that occurs.
On the point of reason, though, humans have had our advanced technology for, say, a couple of hundred years.
The universe is billions of years old. We've basically just learnt enough to realise that technology can do things we can't imagine, and we've only just started. Say a civilization started out a billion years ago. How would we even begin to comprehend what they're capable of? In fact, the human mind, our brains, may be simply too limited to form the concepts to understand reality at a deeper level. And as a species, we might always be like that. So, anything is possible.
I think it's just a question, in practice, of what's the outcome. If alien intelligences revealed themselves tomorrow to the world in a way that was undeniable to most people, and the message was simply, hey guys, you're like small children to us. We don't interfere, but generally, try not to fuck it up. What would we be doing different?
