Eternalism vs Presentism

If eternalism is the idea that the past and the future coexist, and that we are just experiencing a safari - an observation adventure - through a world that is pre-determined, then it means our free will is just an illusion, but time travel would be possible because as "simply" movement along the time dimension.

If presentism is the idea that only the present exists, and that the past and the future are just concepts that we can use to relate to states that have changed and states that we expect to happen, then it means time travel is impossible and that time itself can only be a measure of the difference between states of the present, so that in an absolutely static world with no movement at all it would be impossible to measure time, and in other cases it would be possible for time to be measured differently at different places.

Since no one has been able to demonstrate travel either forward or backward in time, and since a concept of the present is required in order to form concepts of past and future, I believe the idea of presentism has to be assumed to be a better estimation of reality than eternalism; I live in the present and if anyone want to convince me otherwise, the burden of proof is on them!

Animals

I think it's cruel to spay or neuter an animal for any reason other than its own health. Preventing an animal from having offspring does prevent cruelty from happening to its offspring but it's not preventing cruelty to the animal itself. I believe that if a survey were done of humans asking if they believe that they would be thankful for being neutered without their consent because it prevents them from having children who will experience cruelty, the results would be overwhelmingly negative (but maybe not entirely negative).
