If your definition of “aliens” is the mere existence of life on other planets then yes, it is very well possible that there are planets with alien life. Our research for finding life on other planets starts on earth. NASA has been studying a certain type of organism in Mono Lake, California. This specific organism uses arsenic in its DNA rather than phosphorous. The lake it thrives in is one that would be toxic to most organisms. It proves that life can thrive, even in the harshest of conditions, which is exactly what we wanted to hear. This shows that all the extensive research that has been done by numerous universities to see whether or not DNA can exist with different base materials was not in vain.
