A UAP with little aliens could land in the middle of the field during the Super Bowl and people still wouldn’t believe it. Thoughts?

I honestly believe that if all the leaders of the major countries in the world came out and said aliens are real, we have their crashed UAPs, been in contact with them and even brought them on live tv, a good portion of the world would just say it’s not real and it’s a conspiracy to keep us scared. I don’t think it’d be a small percent of people, I think it would be a higher percent, like 30-40.
