Answer:
Beliefs and proof
Explanation:
In my opinion, one of the most hardest challenges that these scientists and Archaeologists face is proof. Is it really the truth? what do i believe? Some <em><u>believe</u></em> that humans originated in Africa over 1.9 million and 135,000 years ago. Note the fact '<em><u>believe</u></em>', have scientists proved this theory of evidence? NO. Do they have human witness of how they looked liked? NO.
All around us there are only theories and beliefs but never proof or evidence.
These are some very crucial factors these scientists face, to be able to actually make people think what they think, to try and convince that even though i may not have proof, our studies and reading are 'vastly' true.
Archaeologists main passion is to understand the past, to collect data and readings, to try and interpret hidden meanings... But have we gotten a conclusion? The origin of man is a very complicated subject. As a Christian i have different beliefs, like others will to.
This brings more frustration for scientists and archaeologists to make space for their beliefs too.
I hope this helps and i hope it cleared a bit of confusion, this is just my opinion.
