Whether it be dissecting what the Kardashians ate for breakfast or understanding why the earth may or may not be flat, seeking to understand the world around us is just what we do as humans. And part of that process is "speculating sensational, justifiable reasons" for why things may be so.
Of course, what is actually worth speculating over is up for debate. As is what actually constitutes a better theory.
But, if people think this is something worth pouring their speculative powers into, they will continue to do so. More power to them.
Now, personally, I'm partly with you here. There is an element of futility in speculating at this stage given the current information we have.
But I'm also partly with the speculators here insofar as the given explanations not really adding up.
