Giants and other species pre-dating Homo sapiens sapiens

• The Universe ("this" universe) has been around for about 13.8 billion years (much longer if one counts its pre-Big Bang infancy as pure potentiality).
• The Earth is 4.543 billion years old.
• There has been biological life on planet Earth for 3.8 billion years.
• The land masses rising above sea (and ice) levels have existed for 750 million years.
• Life has been able to live on land for over 434 million years (plants and fungi acting symbiotically).
• Our current, seven-"continental" formation of land masses has been drifting tectonically to its current configuration for 250 million years. 
• Homo sapiens sapiens--the Latin name our scientists have given to our current humanoid biological life form--has existed for perhaps 100,000 years, "civilized" societies for approximately 10,000-12,00 years (since the Agricultural Revolution).

One would have to be obtuse, naïve, and impossibly defiant to discard the possibilities that A) in 3.8 billion years (or 750 million years, or 434 million years--take your pick) no other sentient life form has ever visited or engaged with the "Earth" planet biosphere, and B) our blip of 100,000 year old DNA represents the sum total of all humankind visited upon this planet we call "Earth."

     I am here to tell you, without hesitation or embarrassment, that there have been other experiments in form stationed and planted upon this (and other) planet(s). The Earth biosphere has served as a fertile and productive testing ground for many extra-spiritual forms serving as vehicles for three- and four-dimensional sentient life experience.

     Like the early experiments with under sea life suits, some of the earlier experiments in human form revolved around housing and mobility: trying to match the contours and limitations offered by the surface (and air and liquid) environments on the planet. Once an acceptable form was discovered (hominid) the levels of sentience, consciousness, and emotional capacities had to be sampled and appraised. Like the form, style, and conveniences integrated into the evolution of the automobile, this process took not only millions of years but thousands of attempts (many imagined, some physicalized). 

     The "giant" form was one that was experimented with. Just as modeling with the imagination is a given skill to most Monads, the abilities of telepathy, telekinesis, and other psi powers were also quite commonly endowed to human models and their numerous prototypes. It was only with more recent model versions that psychic abilities have been backed off in lieu of emotional stressors (commensurate with the more recent trend and desire to deepen the "dive" of the human experiment into conditions of increased spiritual deprivation). In fact, like the diving bell analogy, each incarnate giant was usually planted on the planet where s/he/it would experiment with mobility, construction (creation, art), and interaction with other forms and species, while remaining fully "linked in" to the higher Spirit World the entire time present "on" the planet just as an astronaut or deep sea diver might remain hooked into some communications network with his superiors or collaborators while exploring his "depraved" and "foreign" environment. There were also giant species used to explore more rudimentary skills like physicality, strength, the potentialities for construction, excavation, and physical conflict (fighting and war). Many Monads who participated in the giant experiments continue to use giant forms to this day when interacting with Earth incarnates in an etheric form (i.e., as a ghost, psychic, or dream form).

     I have been a giant. I can still access "memories" of giant lifetimes--including one that was very highly steeped in telekinetic and telepathic abilities. This hominid vehicle had a very immature/undeveloped emotional spectrum to choose from: mostly responses relating to curiosity, amusement (not necessarily humor), and satisfaction. It was, in fact, most interested in and focused upon experimentations within the physical realms of mobility, activity, organization, construction, repetition, and variation (and a little in aesthetics); in short, a very simplistic existence that provided useful information for future development and variations on the theme.
