It would show some clear intent or purpose. As there is no objective evidence of such (or even consensus amongst those claiming evidence), it does not show signs of being designed.
For example, if the universe were designed simply to nurture humankind, it wouldn't be so dangerous. If the universe were designed simply to force individuals to choose between god existing or god not existing, the consequences of such a decision would be clear to
all humans at some point in their life.
So now that I have honestly and sincerely answered your question, please answer just two of mine. Do you believe the universe as we know it was designed? If so, what purpose do you see in this universe?
I will refrain from asking for evidence to support your answers.
At this time.
