This is not a joke. However, even with extraordinary evidence, will you really ever understand?

For instance, examine the results of the "delayed choice double slit experiment." Proove to yourself that the experiment itself isn't just a pre-recording.

Our best human experts tell us that light has a constant velocity for all observers, yet light demonstrates a Doppler effect. How is that possible?

These are just a couple of hints that suggest that human understanding, isn't really an understanding at all.

But having said all that, I am telling you that I have personally seen and communicated with aliens... and of many different types. We live in a world of energy, not a world of matter. They aren't just more advanced than us, they are diverse beyond measure and live in time domains throughout the spectrum. Some are singular entities, and others live in syncytial form in the multitude. They have industry, technology, rural areas and cities, including transport avenues and equipment. The world is absolutely teaming with life, chockablock, overlapped in every sense possible.

In fact, the reality of existence is simply way beyond your wildest expectations. This is not a joke.
