Alright I take issue with both of these statements.
To the first statement: She clearly was referring to the institution of modern science as we know it and not every single discovery made by man.
Except that is not what she said, is it? She said that science is among the youngest of human endeavors. Just because humans did not use the word science does not mean they were not actually using it long before whatever you think modern science is.
When Aristotle postulated atoms he was using science. When the Chinese invented rockets they used science. When the first farmer planted a seed he was using science.
So, whatever you think she meant, she was wrong. Come to think of it, so are you.
To the second: She was again, obviously referring to the religious texts that have been written by man over the centuries claiming to speak for these Gods. So she was saying that there is no written account of any God saying any such thing.
Except she actually said that no god has ever said such a thing, not that no religious text has ever said it. I don't pretend I can read minds, so my only option is to listen, or read, what is actually said.
You clearly have nothing to come back at her with here so you are just picking apart her sentences in any way you can to try and make her argument seem stupid therefore making yours seem superior by default. It's a time honored example of what people like you do when they can't refute an argument on its actual merits and it's rather sad to be honest.
Since she didn't actually make an argument, mocking is all the comeback her words deserve, which is why I mocked.
