Giants existed on Earth.
We really have no idea of our human origins!!
The universe is so beautiful. It is just a never ending series of mesmerizing fractal pattern flowing away into infinity. And so is the story of our earth, the universe it is in. So far with our advancement in science with the field of cosmochemistry we can use radio isotope dating to help the field of earth sciences. So according to the current science on life on Earth was found fairly quickly after Earth's formation 4.2 billion years ago. Researchers from University of Washington, there were fossils that date back to as old as 3.5 BILLION years. That's 3,500,000,000 year's ago from this era.

Keeping that in mind, and the new discovery old gigantic fossils:

It's no wonder anything might have happened between those long periods of time here on Earth that we might have no idea about!
So the existence of Giants with a far advanced ancient technology, and perhaps, multiple other simulations of creation, evolution and destruction of far more civilizations, might have happened before us current human inhabitants of the Earth.
And perhaps it's through "religion" and "myth" that this record-keeping of Earth's past was even done. A prime example for this is the Hindu civilization's "Hinduism". A lot of recent scientific evidence for ideas from Hindu's ancient scriptures has been coming forth recently.
With the existence of multiverses being the biggest revelation in Physics!
So looking at religion, there's a recurring theme of "giant gods" throughout folklore from different cultures around the world:

Now, there is also mind boggling evidence of superhuman feats of architecture in Hindu culture which explicitly depicts Hindu stories in the structures that tell a story of giant gods. This leads to a great scientific case for ancient Hindu puranas to be true. The stories in them might actually have been true and happened right here on Earth in the past!
The literal mountain, Kailasa, was an archeological feat.
Not only that, in Hindu "mythology" (the term now apparently used for ancient historical records), Ramayana, the kind Ravana had advanced technology which has concrete evidence in the current world in the form of "Sigiriya":
Sigiriya is just the surface of what ancient Hindu cultures were able to build.
From Ajanta and Ellora caves to the Angkor Wat temple, these incredible structures cannot be build with current human technology!
Ajanta and Ellora caves were carved into literal mountains, as if 3D modelling renders materialized into rock.
Curiously, there are many conflicts with the whole "out of Africa theory" for the origins of modern human. Truth be told, new evidence is pointing towards ancient human DNA originating from South East Asia, where India is located, which was the site of major Hindu cultures and advanced science and art.
This area was also where the hobbit was as discovered. And, yes. Hobbits existed too. They are called "Homo floresiensis".
Shows how much there is to uncover about our own mysterious origins!
All of this was evidence builds towards how the Hindu "mythologies" of Ramayana and Mahabharata being real life events. Complete with the incredible feats of god like achievements beyond current technological capabilities. What's more, these stories date all the way back to at least 7000 years ago in the past, with much debate going on dating it as far as a million years ago (yikes, a big margin but old nonetheless)!
One more example for this from the Hindu mythology is the "Rama Setu", built by Rama and Vanara's army to cross over to Lanka to rescue Sita, Rama's abducted wife by king Ravana:
So...what am I trying to say? Basically we know nothing about human origins, our ancient ancestor's scientific and spiritual advancement. Many sacred Hindu texts such as the Bhagavad Gita (ancient philosophy), Surya Siddhanta (ancient book on cosmology), Susruta Samhita (ancient book on surgery), Avurveda (ancient plant medicine) and more have profound scientific, philosophical and spiritual findings that are carelessly dismissed as "mythology" in the modern era. Hinduism was a culture of advanced science and art, before it ever was a religion. And, surprisingly, giants were once part of it!
Bhagavad Gita:
Surya Siddhanta:
Susruta Samhita:
Ramayana:
P.S:
Not to mention the giant footprints found throughout the world.
Apparently Smithsonian had a say in a giant cover up. No conclusive proof though.
All of this leads to a fascinating wild conclusion that we actually have no real idea of our true origin as humans. The origins of humans is quiteeee... complicated and shrouded in mystery. Maybe it is time to turn to Hindu scriptures for answers. Who knows! We, in fact, might just be living through a simulation of evolution, and destruction in our infinite parallel, multiversal universe.
