Yes, RNA can form in saltwater. In fact, some studies have shown that RNA can form in conditions similar to those found in salty oceans, which is believed to be similar to the conditions on early Earth. The components needed to form RNA, such as nucleotides, can be found in saltwater, and when these components come together in the right conditions, RNA molecules can be created. This is important for understanding the origin of life on Earth, as RNA is thought to have been one of the first molecules to play a role in the development of life.
