According to evidence found by scientists, where did old stone age people travel across open ocean in rafts or canoes

According to evidence the Old Stone Age people traveled from Southeast Asia to Australia in the canoes or rafts across open sea with no navigation systems present. This was around 70,000 years ago and signifies the great courage and technical edge of the people in that time. 

It shows that people rather save people based on their appearance or their disabilities because they think other lives have more values than others so they try to save the more valuable lives and let the other lives die. This shows that Human beings can be evil or can be good each has their own personalities.
