We haven’t seen alien life, but neither have we seen much of the universe

I propose that going into space is a worthy endeavor on its own without the need to find aliens. The journey of exploration enables us to invent new things that often help our lives on Earth.

"Early expectations of stray radio signals leaking from technological civilizations were overly optimistic—we ourselves have gone radio faint with digitization."

Is this true? Have we been transmitting less RF over time? Where is the data for this?

Who says we haven't seen any ? Maybe we're just looking in the wrong places. There are plenty of reports, paintings, drawings, visions told by people who have been contacted by alien lifeforms, but the scientific community just decides to completely ignore these people, like they don't exist of that they are just telling some fairytales, or labeling these people as crazy.

Think outside the box. If there was an intelligent race of aliens who have invented travel that enabled them to leave their home planets, surely they must have went through some kind of spiritual evolution also not to kill themselves or destroy themselves while inhabiting that planet.

What if, and this is just speculation, this kind of spiritual evolution could also open up whole new possibilities of travel, through time and space, why should they be travelling physically in physical 3D -space, when they could be travelling between time and space, even existing between dimensions.

So we could already have access to these beings and other worlds, but seeing them would not require physical travel, but instead interdimensional travel, through opening up our spiritual side and looking inside ourselves, opening up this possibility for us to travel between dimensions too.

What if we are not seeing them is because we are still so much trying to kill ourselves and other nations, instead of focusing on finding inner peace and spiritual development that would allow us to meet these beings .. ?
