Answer:
ummmmmm.....XD
Explanation:
If humanity was able to sustain life on mars,which is very possible if we create all of the complex life support systems needed but, if there was ALREADY life on mars, I doubt they would be influenced by us, but, confusion and/or fear would be more likely. If they decided to continue living on earth,then they would be affected in order to fit in. They could also possibly contract diseases and sickness that might be causing that fear XD.
