Does this sound like a good opening statement for a debate argument?

Question

I'm in a team where we have to debate the question:

Is man naturally evil?

I'm on the defense side so i have to prove that man is

naturally good, despite my personal opinion.

The statement is only 30 seconds.

I was thinking of just keeping it simple and general.

Something like

We believe that man is naturally good.

But I know that is way too short, so can anyone help me expand that?

I already have my argument, questions, and closing statement, but I need help with my opening statement because I don't want to give away my entire argument in the first statement.

Answer 1

Man is not always evil.

it just has a few evil people,

how can you judge all people?

Answer 2

Underneath the skin, we are all human. And the one thing that makes us all human is the recognition of what is right and wrong. We believe that man is naturally good. As Abraham Maslow once said "The fact is that people are good."
