I think they are already here and have been here like forever. I really wish I knew the real answer to your question. I often wonder why they wont reveal themselves to us, so we can have a real discussion? I do believe our govt. knows more about them and refuses to let us know what’s really going on. Are the aliens afraid that we will harm them? I do believe they are more advance than we are. They either want to research us more, learn more about our planet or just taunting our minds with these questions that are not being answered.
Interesting answer Phyllis. Thank you.
