Let's start with the first asinine assumption here. You haven't established that:
A) The law of thermodynamics apply to a fairly unique event like the creation of the universe, if, in fact there was such an event (and I think we can agree that should it have happened, it was a fairly unique event). It's not like we don't have physical phenomena that only apply either only locally or under certain cir stances (quantum physics, newton's law of gravity, etc).
Establishing that the 1st law of thermodynamics did apply in that event would be a good start.
B) Even if we assume that the 1st law of thermodynamics do apply, then it s on your creator theory, since the creation of the universe would have been merely a transfer of energy from another source of energy (which also couldn't have been created or destroyed, merely existed as a previous transfer of energy).
C) The 1st law of thermodynamics makes no assumptions on a creator. As a matter of fact, it does away with the creator concept entirely. It's just as plausible that aliens inserted energy into a closed system and created the universe as any alleged deity doing the same. It's also just as plausible that the energy was already 'there', and it just combined into, say, the big bang under the right cir stances. Neither you or I know (yet)
Terrible stuff, and frankly it should only take you a few minutes to realize the fallacy of the argument. How we determine what's "present"? How we measure anything really? We setup frames of references. "present" is what we make it out to be based on our frame of reference. We do it all the time. We don't know when time started or when it's going to end. We simply started counting at a given time and that reference gives you the yesterday, today and tomorrow.
There's no mathematical impediment in measuring time over either a finite or infinite timeline. "Infinite" is a perfectly normal mathematical construction.
The example is specially re ed. The only reason a person wouldn't know how much they walked (a measurable event) is because they didn't set a frame of reference when they started. That would be the person being stupid, not a mathematical impossibility.
Do we know wether the universe is finite or infinite, time-wise? No we do not. Is there any mathematical impossibility for it to be infinite, no there is not.
And finally we arrive at drawing conclusions over flawed assumptions, more typical stuff from science hacks that gloat about high IQ.
If only you actually spent more time learning about what you post you could've saved yourself the embarrassment, tbh.
