Alternative explanations are always welcome in science, if they are better and explain more. Alternative explanations that explain nothing are not welcome... Note how science changed those beliefs when new data became available. Religions stick to the same ancient beliefs regardless of the data.

Debating is not an honest intellectual exercise. It's like a trial in which the goal is not to get to the truth but to win.

Until recent times, absence of evidence for his [Jehovah's] existence has not been sufficient to rule him out. However, we now have enough knowledge that we can identify many places where there should be evidence, but there is not. The absence of that evidence allows us to rule out the existence of this God beyond a reasonable doubt.

The battle over the validity of evolution has been publicly posed as a scientific one. However, you will find little sign of it in scientific journals, where such quarrels as exist are over details, not the basic concept... Evolution has proved so useful as a paradigm for the origin and structure of life that it constitutes the foundation of the sciences of biology and medicine.

People want to be at the center of the Universe...and they're going to flock to anybody who tells them that.
