The biggest argument against Aliens is that, any civilizations which has technology capable of travel at the speed of light, would have developed almost real life like VR. And no point in traveling all the way physically to another planet when you can experience it in VR from your home planet.

Plus by that point the civilization would be so advanced, the beings would no longer be tied to legacy biological physical bodies. They would be living in the "cloud". And would probably does not give a shit about Physical beings like us.
