The extra terrestrial as you may call them, or aliens are species that existed thousands of years alongside you in another physical reality. But who are they exactly?
You have been wondering and searching to find these species as you are reluctant to understand their existence and with that your very own. One the one hand you search them in anticipation of the knowledge they will bring, and on the other hand you fear of their intentions, of their power against you. For this, a “wall” was created to keep them and you from constant interaction.
They exist in another ultimate reality, or dimension, close to you own and live by both physical and spiritual reality, like you, but with few exceptions. They do have a physical shield but they are mostly spiritual with mind powers well established and practice among all of them that now have exceeded their need of a physical body. They were once, like you, physical but they have evolved in spirit, and can use powers like empathy to talk to one another. They do not use speech like you. Mostly similar to any spiritual being that communicates without a voice. Their intentions are very clear and they are exceptional manifestators as they are not shadowed by an ego self. They are in clear and constant interaction with their spiritual natural that allows them to interact and use the force of the universal energy for their benefit. That does not mean they are evil, are need to be feared. Like you there are good beings but also those who have lost their way. Their overall energy however, is the one of bliss and peace and this is how they wish to remain. Due to their evolved nature, they are more evolved in many other fields as well but mostly, they do not care of physical matters nor technology but wish to expand in spirit. They hold more powers like telekinesis and what you call Teleportation to move. All that they have is but what you can achieve also and you have began to turn towards spiritual evolution.
They respect your human shields and energy and do not want to frighten or disturb you but they are very eager to meet and interact with all that you are. They observe your progress and are very eager to appear whenever you are ready to meet. Your interaction with them will once enlighten and awake you towards your spiritual powers. However, not all are ready yet for such an interaction and for this they choose to remain hidden. Do not be afraid of their existence as they are only like you but more evolved in nature. Your constant search for the extra terrestrial as you call them, will not be of fruition as they cannot be seen unless they want to.
Do they live on earth where you are? Do they abduct people?
As they are keen to know of your nature as well, they have and do observe mostly without harming you. However their search ended as they no longer interact in fear of a negative relationship. They know observe, uninterrupted your free will and asking to appear to whoever is ready for the interaction. Their message to you is “we are here, we do not wish to harm, we come in peace”.
