Why is that? Why would you not see reality as it is? What is wrong with the idea of space and time as the foundations of the solid world that surrounds us?
The problem lies in the perspective and if you are interested in truth than you have to make sure that the biological setup of our body is actually tuned to perceive reality as it is.
But it turns out, the goal of our bodies during evolutionary times was not to see reality for what it is. The goal was simply to improve the likelihood that you successfully produce offspring, which then itself can go on to reproduce. It is therefore not at all in our biological interest to see truth. And we are therefore not equipped to do so.
I want to share with you here an interesting talk about 3D-Space. 3D-Space is in this model only the way we get presented with the raw data of our environment so that we can best process the information.
Without going further into it, here is the video. It is worth watching in it's entirety. It gets very interesting towards the end.
