What if the universe was......?

It is certainly possible. The idea that the universe was created on purpose, with a specific generic end in mind, has no real support in actual evidence, but it is not an impossibility. Just no cause to think it is true. Of course, if you wish to postulate that the "creator" had very specific endpoints in mind, that is very difficult to envisage. There is too much chaos to be that specific at the outset, even with a presumably all-knowing entity ("all-knowing" is essentially an impossibility). The arrival of a specific man? cannot see that as possible. but the idea of seeing some sort of intelligent life coming into being? that is almost a given if enough time is allowed.

We can speculate, but it is unlikely we will know before 2099. No engineering in progress is likely to get us even 1% of a light year from Earth in this century.

no, not merely a microbe, we are 1000 times smaller than neutrino. no, with speed of light rockets it will take 93 billion years to travel from one edge of universe to other.

One argument against the "Anthropic Principle" is that our Universe is much, much bigger than the minimum size needed to generate us humans.

"designed" and "meant" both imply purpose. That is by no means axiomatic.

You just figured that out?
