Of course. Educated atheists or anyone who has like you said basic familiarity knows this like ABC. Just that, as said it's a linguistic reading that some think IS the philosophical meaning and argue about it like there is no tomorrow.
There is no tangible proof that there will be a tomorrow, since it is not yet manifest in time or space-time to collect any hard data for hard proof. However, we all have faith in tomorrow, since day and night have physical explanations and there is no foreseen disasters that would suggest otherwise. Still science cannot prove tomorrow, today, using its own philosophical methods. At the same time, since tomorrow is very likely, any theory will work, since all theories will have the same tomorrow, as proof. The black box oracles of statistics are often used to predict tomorrow in science. We can also use rational equations based on cause and effect.
We live in space-time. Conceptually if space-time was separated into space and time, where each can act as independent variable, instead of co-dependent as space-time, this would allow more options, many of which express the classic nature of God. If you could move in space unconstrained by time, you could omnipresent. This simple math assumption, taken to the limit, can predict classic godlike attributes. Science is not yet advance enough to use this new math assumption properly. It can do what black box oracles do, but in a more accurate rational way.
Proof of independent space and time can be seen via the Heisenberg Uncertainty Principle;
Formulated by the German physicist and Nobel laureate Werner Heisenberg in 1927, the uncertainty principle states that we cannot know both the position and speed of a particle, such as a photon or electron, with perfect accuracy; the more we nail down the particle's position, the less we know about its speed and vice versa.
The simplest way to explain this is space and time; position and motion, respectively, are not connected exactly as suggested by space-time, but rather space and time are each showing some independence of each other. It is that simple. Advance physics can now be taught in kindergarten leading to a very bright future in the field.
The Heisenberg Uncertainty Principle is where much of science left the track and became less rational. The uncertainty principle is often used as a justification for statistical uncertainty within nature and the quantum state. That is one interpretation, but that can be debunked. The Heisenberg Uncertainty shows that the more accurately we measure position or momentum the less certain the other variable. That is a statement of determinism and not randomness; simple inverse relationship. Ignorance as to how this actually works, is not the same as random, and the whims of the Gods. How it works is based on separated space and time. It is that simple.
If the uncertainty principle was a true example of randomness, some experimental days the two variables would match and other days they would be way off and also in different amounts. But there is always a reverse relationship; closer and farther. The golden age of Physics was the 1920's before science derailed to use the math of politics, marketing and casinos. We are stuck at random derivatives.
This simple change to both space-time and separate space and time, allows one to rationally explain the quantum state, address the nature of God and even the framework of life and consciousness.
Imagination can exceed the material limitations of space-time. I can pretend to fly to the sun with wings of wax and not get burnt. This cannot happen in space-time, but it can happen if space and time were not connected; fiction and imagination. Innovation is often a blend of the two. However, innovations become the most useful, when what remains is consistent with the limits of space-time. The bugs are connected to separated space and time and are often used as scaffolding. The job is not done until the scaffolding is removed. The ancients would attribute this blue print and scaffolding process to the gods; separated space and time, influencing space-time; build the pyramids. This gave the blue print and the drive, until space-time reality was molded to the visions, and remained in space-time.
Opening the philosophy of science to deal with internal data allows for learning about separated space and time, since the brain evolved within space-time with it hooking up with separated space and time; consciousness. With humans, staying in reality; space-time is often the challenge since the other side has way more options; human spirit in separated space and time. Faith in visions of paradise.
