science may have created the atom bomb but that is not to say they condoned its use.
Albert Einstein is quoted with the following after Roosevelt approved the Manhattan Project due to Einstein's letter: "I made one great mistake in my life—when I signed the letter to President Roosevelt recommending that atom bombs be made; but there was some justification—the danger that the Germans would make them."
The motivation behind this Project was to compete with Nazi research for their advancement in atomic bombs. Einstein advocated for a pacifist world, but he knew that German researchers were creating lethal weapons for the wrong people.
The use of the atomic bomb of Hiroshima and Nagasaki was not initiated by scientists but as a retaliatory strike followed through by US governing powers.
The destruction created by science and research has almost always been in the hands of military and governing powers.

Now let's look to religions. The massive amounts of deaths span for centuries over beliefs and pride that one's santa claus is more real than another's easter bunny. There are numerous massacres and fruitless wars to provide support for this, but I would like to address the crusades. These Crusades lasted from 1100 to 1600. That is 500 years of ongoing battles over what? Assertion of who is right over their beliefs more than their neighbor? Hundreds of thousands were killed as women and children were also motivated to fight for the just cause. Pope Urban II told these recruits that if they took back Jerusalem from the Muslims they would receive remission of their sins or even heaven after death (there's controversy over this, but regardless, it's ridiculous).
People complain nowadays about fighting wars for our government, our freedom and peace for others. Imagine slaughtering your own neighbors because your priest told you that you might go to heaven (a place that may not exist).
Religion proves great for literature, history, and philosophy but logic will always supplant belief.

The issue with religion is that it always has to be right. There is no middle ground, there is no room to allow for different lines of thinking. It doesn't change and adapt with the times. A prime example of this is the Vatican and its views on contraceptions. Muslims stoning women in the streets in 2012. [List more]
Religion forces one-dimensional thinking. This leads to close-minded bigots headstrong on how much more realistic their deities are and how they are never wrong.

The beauty of science is that it advocates critical thinking. It forces you to question the theories and thought processes of your peers as well as yourself. Theories are awesome because it allows you to be wrong. Nothing is ever set in stone and all statements can be challenged at any time. The best thing is that many scientists enjoy having their assertions challenged as it provides greater perspective, research, and information in their field. Peer review is not perfect, but it's a beautiful tool in the realms of research.
Science advocates questioning and critical thinking while religion throws you to rot in a tower for asserting that the world is round.
