RNA is needed because it serves as the messenger that carries genetic information from the DNA in the cell's nucleus to the ribosomes where proteins are made. RNA is also involved in other important cellular processes such as gene regulation and protein synthesis, making it a crucial component in the overall functioning of the cell despite the presence of DNA.

How could all three of them have come into existence at the same time since RNA DNA and proteins all need each other for life to continue?

RNA doesn't need proteins nor does it need DNA. RNA probably came first. And it is known that RNA can form peptide bonds which can make proteins. DNA would have come later. They don't need each other, from an evolutionary standpoint. Modern DNA and RNA and proteins are interlocked, but earlier forms clearly weren't.
