Is there ONE prayer that can literally save humanity and the world, if we can simply get enough people to repeat it SINCERELY,” something that can be spoken by people of any religious background, people who differ not only in race and culture and upbringing, but also intelligence and comprehension?

Any such compromise will truly be a compromise, so you are asking the impossible in a strict literal interpretation of your question. There is too wide a spectrum to incorporate everyone under one small umbrella. The intent of the question is not unsound and for the practical application you seek it is wise to consider the importance of each and every word of such a prayer request to do the best one can. So we would offer the following: “Source Creator, be my partner in life each and every day, to keep me focused on love, receiving and giving, both to myself and to all those around me.” This is the essence of our message. As love is the currency in all healing, and as healing is the answer for the threats to humanity, a love-focused prayer will allow us the broadest possible reach and latitude to assist all those who make such a prayer request. For serving them in a way highest and best would certainly encompass helping them to survive an unexpected eventuality, unless there is a prior alignment with these dark forces in some way. That is, in fact, the case for many current humans. Although for the most part it is an unwitting association, they are nonetheless under the spell, so to speak, of the darkness, and their focus and vibration render them unreachable even by Creator’s love. This is where you come in—to spread the word. Humans have a personal responsibility in seeing to their own circumstances, and in particular their own healing, especially when it comes to enlisting the aid of the divine realm, so they are truly ready to interact with us with the requisite belief quotient, not just the right words, as that will be the greatest impediment. Second to that is the limitation inherent with their inner negativity towards themselves—to believe their worthiness to have a divine intervention just for them is a great leap and a practical gap for many in receiving divine help at all. Some coaching will help with this, but as you understand, many will need deep healing work to enable them to participate in a meaningful way. That cannot be addressed through a simple broad prayer request outreach or teaching outreach. But the more people who make the attempt, the further the gains will be made in the Shift in Consciousness. And even those functionally not ready can begin a process of healing to head in the right direction, and that may pay off in the future.
