Actually Jan, just about all of us started off building temples, then, we moved up in levels and struggled. So we read the forum, we tried playing without temples, and it actually made the game easier. Then, we moved up further in levels, learnt even more about the game, so that now we can determine for ourselves when building temples is good, and when it is not. However, one thing we do know through experience, is that building temples is not the best strategy in most cases, that's why we like to give that advice.
So yes, there are alternative strategies that involve temples. There are certain civs, certain map layouts, certain game situations, certain win conditions where building temples is good, but in general, no temples = a easier time winning the game
