First of all, I'm going to point out that it should be, "Did Abrahamic religions
ruin the world?", because I'm a picky bastard.
To answer the question, no I don't think they did. In terms of wars, whilst many were caused by religion, I think in many cases it was simply an excuse (and a way to keep up morale) and conflict would have broken out anyway.
And even so, would the world be better now without those wars? I doubt it. The high death rates slowed the rate of population increase, without which we would have a massively increased population. This would lead to an even greater food shortage than we already have, not to mention the huge amounts of extra energy we would be consuming and the subsequent climate change issues.
In terms of scientific advancement, while it is true that Christianity has often been rather closed-minded, and violently opposed changes to what they believed was right (take Galileo as an example), that was not always the case, and Islam have always been pretty good about collecting knowledge. The Romans were a Christian nation (near the end of their rule) but were amazing architects, and built and maintained many useful facilities across their territory, which only fell into disrepair after the fall of the Roman empire (which was mainly down to the sacking of Rome by pagan raider).
As for Islam, after the fall of Rome, they collected many of the surviving books on medicine and science and stuff, rather than burning it, as some people did. Not only that, but they made copies of it and translated it into several languages, as well as making improvements on that knowledge. In addition, they did not keep that knowledge to themselves, but sold it back to Christian nations, as well as other nations, thus spreading the knowledge once more around the globe.
As for Judaism, I'm not sure of what their effect on Scientific advancement has been as a whole, but that in itself is evidence that it may be negligible.

I don't think that judaism should get a easy pass solanin, they had direct influence on the creation of Christianity and Islam.
So? One could argue that Judaism also had a direct influence on Hitlers persecution of the Jews, but I would hardly think that they should get the blame for the Holocaust.
