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.

Assuming the universe came from nothing, it is empty to begin with... Only by the constant action of an agent outside the universe, such as God, could a state of nothingness be maintained. The fact that we have something is just what we would expect if there is no God.

While science continually uncovers new mysteries, it has removed much of what was once regarded as deeply mysterious. Although we certainly do not know the exact nature of every component of the universe, the basic principles of physics seem to apply out to the farthest horizon visible to us today.

Nature is capable of building complex structures by processes of self-organization; simplicity begets complexity.

Any strategy that attempts to reinforce faith by undermining science is also doomed to failure. Showing that some scientific theory is wrong will not prove that the religious alternative is correct by default. When the sun was shown not to be the center of the universe, as Copernicus had proposed, the Earth was not moved back to that singular position in the cosmos. If Darwinian evolution is proved wrong, biologists will not develop a new theory based on the hypothesis that each species was created separately by God 6,000years ago.

To most theistic believers, human life can have no meaning in a universe without God. Quite sincerely, and with understandable yearning for a meaning to their existence, they reject the possibility of no God. In their minds, only a purposeful universe based on God is possible and science can do nothing else but support thistruth.

When people start using science to argue for their specific beliefs and delusions, to try to claim that they're supported by science, then scientists at least have to speak up and say, You re welcome to your delusions, but don't say that they're supported by science.
