An interesting comment! I have read this thread thus far and have to ask what item of information leads you to suppose that ETs are here, amongst usQuote
My belief in ET's is based mostly on faith much like religions.
A book my reader finished a few weeksago, and which we both found extremely interesting, is called 'Living With The Stars' by |Karel and Iris Schrijver (you may have seen my mention of it already). I set the facts contained therein against any speculation about the possibility of inter-galactic travel, and I'm sure you know this, but I ask the above question seriously and await with interest your response.
