Hebrews 11:3  (KJV)   Through faith we understand that the worlds (aion) were framed (katartizō-made perfect) by the word of God, so that things which are seen were not made of things which do appear.

God giving a hint  that all things were created by things that are not visible-God-and this may even hint that God ‘stood’ in the spiritual realm to do it. ‘Framed’ apparently meaning imagined/planned. lKat Kerr. Note how  worlds is plural.
