In the same way the universe is somewhat kind of doomed when it's entropy will be at it's maximum. Does this not also tell us that it must have had a beginning ?
This is not an end to the universe. This is just another phase the universe enters into where it entropy has maxed out (if 100% entropy is even possible). It is not like when this happens a magical clock strikes 12am and the universe disapears or ends.
Douglas Adams in 'The Restauraunt at the End of the Universe' writes:
Ladies and gentlemen," he said, "The Universe as we know it has now been in existence for over one hundred and seventy thousand million billion years and will be ending in a little over half an hour. So, welcome one and all to Milliways, the Restaurant at the End of the Universe!...
"But what about the End of the Universe? We'll miss the big moment."
"I've seen it. It's rubbish," said Zaphod, "nothing but a gnab gib."
"A what?"
"Opposite of a big bang. Come on, let's get zappy."

One of the saddest lessons of history is this: If we've been bamboozled long enough, we tend to reject any evidence of the bamboozle. We're no longer interested in finding out the truth. The bamboozle has captured us. It is simply too painful to acknowledge -- even to ourselves -- that we've been so credulous. - Carl Sagan, The Fine Art of Baloney Detection
"You can't convince a believer of anything; for their belief is not based on evidence, it's based on a deep seated need to believe." - Carl Sagan
"It is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring." - Carl Sagan, The Demon-Haunted World
