False. TRUTH is greater.
Story:
A young woman goes on a cruise. She meets a single man who is a Heart Surgeon from New York onboard. They spend several days together, getting to know each other, laughing, sharing stories. She begins to think to herself "this man might be the one" and by the end of the cruise, she is convinced he is the one for her, and he also professes the same sentiments. When the cruise ends, they get off the ship and she sees him immediately walk over to his wife and their two children, giving them big smiles, huge hugs and loads of kisses before they all return to his life as a car salesman in Kansas.
Love without Truth is a lie.
TRUTH is the FOUNDATION.
Love, Real Love only has lasting power and force when it is built on top of Truth.
You should question the Truth of the claims by those "advanced races" you speak about.
