Hi guys, great show, havent chatted for a while been up to my eyeballs in work
I can only give my opinion for what it is worth, i think its fair to say that most of us end up chatting in a place like the paracast because we are fully accepting of the fact that we dont have the answers to life's big mysteries.
So i'm somewhat wary of people pushing their weight around and concentrating heavily on the idea that they know better, when in reality, in the grand scheme of things we are but a race of individuals, none of which have ever had a good handle on the inner workings of the existence around us.
For me that makes the subject of 'what we dont know' a fascinating one, in fact i think i would go as far as to say that you could fill a whole universe with the things we dont yet know or understand.
This is where i personally find the ETH interesting. I think most people are in the general agreement other life exists in the universe when taking the scale into account, so for the ETH to have any grounding you would be looking for motive & opportunity.
Opportunity is effectively technological capacity, i appreciate that alot of counterintuative thinkers (be it subconsciously or otherwise) like to consider human technology/understanding as a starting pinnacle and quickly conclude that the technological capacity is not available to any being to make such a trip. But when you consider we have only embraced civilization in the last few thousand years, only travelled outside our own atmosphere in the last 50 years or so, when you compare that to the potential of billions of years of tech advancement made by others - i dont think we as a race are in any position to be shouting that odds about what is or isnt possible.
As far as motive goes it could be any number of things, zipping from one part of the galaxy to another could be equivalent to driving 5 miles down the road for an advanced civilization, and if you are talking millions of worlds, you could be talking billions or trillions of active travellers. I could quite imagine that any race with a couple of billion years on its hands may well have stumbled across our neck of the woods at some point. At which point we become just another point of interest on the galactic google star map.
So when i hear someone say, or even manage to get a video of something that they feel seems out of place / not able to describe as a known craft, people can argue till the cows come home over the finer points of what did or did not happen, but logically speaking the concept that it not only could happen, but happen on a regular basis is of no suprise IMO.
