Is it true that a comet caused the Tunguska event?
Unclear. Several sources report that many scientists believe a comet caused the Tunguska event, and some research advances a cometary airburst hypothesis, but the reference overview notes the asteroid-versus-comet question is still debated. The evidence supports the comet explanation only in part, not as settled fact.
