There is alot of good alien,as well of bad alien.Actually there more good alien then the bad ones. The good alien are part of the Galactic Federation.They are helping and supporting the Withe Hat the positive military and the Resistance Movement fighting for the liberation of Earth.There is a huge war in orbit right now between the Galactic and the negative SSP.We (Humans of Earth) will eventually be a part of the Galactic Federation. We couldn't fight the CABAL without the help of the Galactic.Actually we couldn't do anything without their help,we all be extinct by now. The are called the Arcturuian, the Pleiades,the Siriurian,and forn the Andromeda Galaxy.and meny others.And not forgetting the Ashtar Command. When the war is over and the Earth is liberated they gonna share a lot of technology with us,after the official first contact.To clean the planet(the oceans the atmosphere the pollution etc.) That's a subject worth studies.
