What's your point? You can't logically argue that science is wrong all of the time just because some scientists were wrong once, or changed their theories as new data and modeling were available.

Your turn - what do you believe, and what is your basis for it?

You never change things by fighting the existing reality.
To change something, build a new model that makes the old model obsolete.
