It is not logical at all. Nothing speaks against contingent things caused by other contingent things. Ad infinitum.A necessary being is a being that exists necessarily. Online lets say our earth. It came to being some time ago. Maybe billions of years ago. So its contingent. Thus, when you go back in regression, logically it goes back to a necessary being.
So, when you say “logically” what you men is “logically for me”
it is a bit like when you say “irrelevant”. What that really means is “no idea how to reply to this”. Right?
