Well let's not get ahead too much. Suppose such a civilization has existed in another galaxy, there is probably very little chance that they would be able to jump to another galaxy. The distances are huge.
And there is also the possibility of having intelligent civilizations never reaching the space age for one reason or another.
We have only ONE specie on Earth among billions which reached this point, it is not like we have much of a sample to make any rule.
All this is just assumptions based on very small data pool. Meaningless.
